Bieber joins Viddy, posts hot, topless video… of himself

Oh, boyfriend. Pop superstar Justin Bieber has joined video-sharing sensation Viddy.

The “Boyfriend” singer took a mini break from promoting his coming-soon album “Believe” on Twitter to solicit a little Viddy love from his almost 22 million Twitter followers — and give back a little something with footage of himself shirtless at a photo shoot.

Viddy is the Los Angeles-based startup that makes an iPhone application for shooting 15-second clips that can be enhanced through “production packs,” otherwise known as video effects. The service, which has more than 27 million users, is often likened to Instagram for its ease of use and simple sharing tools. The company just announced a massive $30 million funding round.

“Photoshoot was….well u will see. #viddy #abouttogoIN,” Bieber tweeted Tuesday afternoon. “Follow me on @viddy – @justinbieber,” he added.

Just a few minutes later, the teen heart-throb posted his first Viddy — an update of himself shirtless (we’ve confirmed that “justinbieber” is his official account). Clearly, the Biebs knows what the ladies like. The account added more than 3,000 followers in the first few minutes following Bieber’s tweets, and the viddy is racking up comments and likes as we speak.

The Biebs joins a growing cadre of celebrity Viddy users — some of whom have actually decided to invest — sharing stylized quickie vids with their fans. Viddy celeb members include Bill Cosby, Rihanna, Snoop Dog, Terrell Owens, and newbie Katie Couric. Even Facebook CEO Mark Zuckerberg recently got in on the Viddy action.

Viddy has more than 27 million registered users, and is adding 500,000 new users per day. It feels like it wasn’t that long ago when the startup first announced hitting 10 million users — oh wait, it wasn’t. In fact, just a little over two weeks ago the service touted the 10 million milestone. Today, that seems like small potatoes.

With Bieber on board, who knows what crazy member-milestone the company will surpass next.
