The Huffington Post Media Group, AOL’s fast-moving content unit, is launching a celebrity site called HuffPost Celebrity today, as well as another called HuffPost Culture.

HuffPost Celebrity, which ate AOL’s former celeb-focused site PopEater, is described as “an insider-y look at entertainment and celebrity, with the latest news, original reporting and scoops from our team of reporters.”

While the Huffington Post has always had a huge dollop of celebrity news and blogs, it puts the much more focused site into a very crowded arena online, with competitors such as Yahoo’s omg!, Time Warner’s People magazine Web site, as well as AOL-owned TMZ.com.

That means a major focus on the news site’s mix of short and juicy items, blogs of the famous (and infamous) and lots and lot of videos and photos.

And, indeed, the new site, which can be viewed here, has that. The main feature now is a big photo with the title, “PHOTOS: Gaga Arrives Down Under” and blogs by Jon Favreau and Tracey Ullman and slide shows of “Kardashian Bikini Show & Tell” and “Child Stars That Avoided ‘The Curse.’”

The move is another of a series of them in an aggressive expansion of AOL’s content offerings under its chief, Arianna Huffington (pictured right), who now has the money and staff she has obviously long wanted to blow her online media empire out.

And it is clearly yet another sign of the reliance AOL now has on the media group’s platform, since it bought the Huffington Post for $315 million in January.

She recently launched a U.K. edition of the site, for example, and has pushed out a number of new categories as the HuffPost has subsumed all of AOL’s previous content efforts.

Here’s the official press release on the latest launches:

AOL HUFFINGTON POST MEDIA GROUP ANNOUNCES LAUNCH OF TWO SITES: HUFFPOST CELEBRITY AND HUFFPOST CULTURE

Entertainment News Site Goes Live Today, Arts Destination on Wednesday;

Both With HuffPost’s Real-Time News and Opinion, and Leading Edge User Engagement

“HuffPost Celebrity Network” Syndication Feed Launches Today

New York, NY (July 11, 2011) — The AOL Huffington Post Media Group, a leading source of news, opinion, entertainment, community and digital information, announces today the launch of two destination sites: HuffPost Celebrity (huffingtonpost.com/celebrity), a lively mix of real-time entertainment news, opinion and gossip, and HuffPost Culture (huffingtonpost.com/culture), covering a wide span of the arts, from theatre and film to music and dance. HuffPost Celebrity goes live today and HuffPost Culture launches Wednesday.

Both sites offer The Huffington Post’s unique combination of real-time news and opinion, and a passionate and engaged community powered by the latest social engagement tools. HuffPost Celebrity also features a syndication platform offering the latest entertainment news and blog posts to partner sites. HuffPost Celebrity is edited by Katy Hall, Managing Editor of Entertainment of AOL Huffington Post Media Group; HuffPost Culture is edited by Gazelle Emami, Culture Editor of AOL Huffington Post Media Group; and both sites are being overseen by John Montorio, Editorial Director, Entertainment, Culture & Lifestyle of AOL Huffington Post Media Group. Arianna Huffington, President and Editor-in-Chief of AOL Huffington Post Media Group, made the announcement.

“We’ve always offered a take on celebrity and culture that is a fun, high/low mix that reflects our users’ diverse range of interests and desire for comprehensive entertainment news delivered in real-time. Creating these two new destination sites will allow us to both expand and deepen our coverage,” said Arianna Huffington. “Our goal is to give our readers everything from buzzy items to thought-provoking opinion pieces delivered with a style and a voice that’s uniquely HuffPost. We want to inform and entertain, while engaging our community around these subjects and serving as a starting point for compelling ‘digital watercooler’ conversations.”

HuffPost Celebrity is an insider-y look at entertainment and celebrity, with the latest news, original reporting and scoops from our team of reporters. The site is accessible, fresh, and filled with the kinds of stories our readers love to share. HuffPost Celebrity encourages users to engage with stories and features the most up-to-the-minute photos, videos, slide shows, and blog posts from industry executives to celebrities, all weighing in in real-time. Among the talent that has blogged on The Huffington Post are Alec Baldwin, Scarlett Johansson, George Clooney, Madonna, Ryan Reynolds, Larry David, Bill Maher, Rob Lowe, Russell Simmons, Natalie Portman and more.

HuffPost Culture will complement our entertainment coverage, delivering a one-stop-shop for all that’s happening in the performing arts, visual and broadcast arts, including dance, opera, music, architecture, film, TV, photography and more. The site will have visually arresting images of performances and art pieces with HuffPost’s singular style of coverage, including original reporting, artist profiles, reviews, interactive infographics, sneak peeks, slide shows, videos and more. HuffPost Culture will be a forum for discussion of arts and culture, and serves as a guide for users wanting to stay abreast of cultural news and events.

The site will offer a number of ongoing features meant to explore the arts from all angles. For example, as part of a “Strange Bedfellows” series — following unexpected collaborations between artists — HuffPost Culture will offer an exclusive video collaboration between David Lynch and the band Interpol; “On Our Radar” will highlight emerging talent; and profiles of artists include an “Architects in America” series. HuffPost Culture will feature exclusive playlists from musicians and DJs, starting off with a summer playlist from Chromeo. The weekly “Culture Forecast” will serve as a handy guide to what’s happening in arts and culture. At launch, HuffPost Culture will offer different best-of-the-year-so-far picks, from music to art exhibitions. In addition, HuffPost Culture will present curated content from AOL sites such as Moviefone and HuffPost Celebrity, as well as the best arts coverage from around the web.

The launch of the HuffPost Celebrity Network today offers media partners syndicated, constantly updating entertainment content available for use across a wide variety of platforms. Participating partners include SFGate, Tribune’s Zap2It, and Russell Simmons’ Global Grind. “HuffPost Celebrity demonstrates our ability to combine compelling content with a platform centered around user engagement, while our new feed, the HuffPost Celebrity Network, shows how we can most effectively leverage our unique assets,” said Kerry Trainor, Senior Vice President/General Manager, AOL Entertainment. “We make it turnkey for our partners to offer their users the highest quality entertainment news, whether it’s for the latest tablet or a long-standing website. We want to offer a vibrant distribution feed that reaches a wide audience for our content, while enabling our partners to engage their users around it as well –- it’s a classic win-win.”

The British version of the Huffington Post, which has been expected, went live today.

It is the site’s first major international expansion beyond North America (Canada was first).

While the content is aimed at the audience there, it will still have the usual HuffPo mix of saucy news, videos and blogs.

But in this case, instead of U.S. celebs and pols, those blogs will come from famous British luminaries, including former Prime Minister Tony Blair; Sarah Brown, wife of another former PM, Gordon Brown; and entertainers Ricky Gervais and Tracey Ullman.

The Huffington Post apparently already attracts a monthly audience in excess of 1.2 million in the U.K.

AOL — which bought the high-profile news and opinion site for $315 million — has given its content head, Arianna Huffington, a lot of backing and also funding for expansion, including globally.

Other international Huffington Post sites are likely to roll out soon.

Here’s the official press release:

This past Saturday night, BoomTown attended the tony San Francisco book party for Jonathan Zittrain’s new book, “The Future of the Internet–And How to Stop It.”

It was hosted by megablogger Arianna Huffington and Melanie Ellison, an old friend of Zittrain’s from high school, as it turned out.

And BoomTown took our Flip video camera, of course.

For one, it was held at Ellison’s stunning Pacific Heights home, with a lot of Internet and San Francisco wattage in attendance, including Melanie’s husband, Larry Ellison, and Mayor Gavin Newsom.

By the way, Zittrain is professor of Internet governance and regulation at Oxford Internet Institute, Oxford University, and co-founder of Harvard Law School’s Berkman Center for Internet and Society.

And the book is actually not about stopping the Web–perish the thought, as what would I do with my life without my beloved Internet, which I would marry if it were legal?

Instead, according to Zittrain, my beloved Web is in deep, deep trouble!

He is justifiably worried about innovation continuing and the book is a bracing call to fix some of the Internet’s serious structural and other problems, before it collapses in a giant heap of too-tightly controlled mundanity.

I’m for that! Let Web Wackiness Worldwide (WWW!) reign!

In that spirit, here is a video of the party, in which I ask everyone the key question: What is the future of the Internet?

The video includes some book party speeches and thoughts from Craigslist’s Craig Newmark, Jim Steyer of Common Sense Media, Accel Partners’ Jim Breyer, Techdirt’s Mike Masnick, Zittrain and, of course, Huffington (and I also got her to impersonate Tracey Ullman impersonating Arianna to up the wacky quotient) .

And also three Internet clowns trying to impersonate me. Wackier still!

Here’s the video (there is an odd voice/video disconnect in the Zittrain and clown sections at the very end that I am trying to fix):

The British comedian does spot-on impressions of average people and the errant celebrity too, including a pitch-perfect one (right down to yelling for her sister Agape) of blogger Arianna Huffington with the signature line: Blogs and Kisses!

And in this video, accepting an award at the Bloggies, the hysterical moment when Ullman/Huffington tells a competing right-wing blogger to have her “YouTubes tied.”

Here’s the video and also the promotional one for the show that is pretty funny too:
