Justin bieber tweets topless picture from bed, teenage world implodes

Justin Bieber has revealed a new tattoo - done so in the now traditional online manner, a self-shot topless photo taken on a bed. See the photo below.

The sound of millions of teenage girls exploding could be heard across the world when Bieber posted the photo on Twitter on Friday night (31 August, 2012). Fans were quick to respond to the 'Boyfriend' star, ignoring the new ink on his chest and mostly responding saying "OMG UR SOOO HOT!!!"

The Canadian star previously showed off a new tattoo in July 2012, having a tiny tattoo on his right arm, the Japanese symbol for Kanji.

When the young star isn't sharing topless photos online or having miniscule tattoos, he has spent much of 2012 causing controversy, most recently suggesting that Prince Williams used growth hormones to restore his thinning hair. He also angered US aboriginal groups by suggesting that his inuit heritage entitled him to free 'gas' in Canada.

"I'm actually part Indian," he said in an interview with Rolling Stone in July this year. "I think Inuit or something? I'm enough per cent that in Canada I can get free gas."

His comments caused anger with the Congress of Aboriginal Peoples. “We have enough issues with racism and stereotyping,” say Dwight Dorey, the congress’s national vice-chief, in the statement. “A young, high-profile entertainer like Justin has a huge following. He has a major impact on young people. That concerns me.”

Miley Cyrus’ Tattoo Timeline: What’s the Meaning Behind Her Ink? (PHOTOS)

Last week, the 19-year-old “Party in the USA” singer stepped out and showed off some brand new ink on her forearm, which consisted of Roman numerals VIIXCI (7 and 91). While the jury is still out on what her new tat means, Celebuzz decided to break down the meaning behind her other various tattoos. If you remember, Miley got her first tattoo at the age of 17, which reads “Just breathe” on her rib cage.

Any guesses as to why she went with that particular message?

A family friend of Miley’s suffers from cystic fibrosis, and dedicated her first tattoo to them.

Miley then followed up with some smaller tats, including an anchor on her pinky and “love” on her inner ear, but then got one of her largest ones to date — a dream catcher on the right hand side of her rib cage.

From wizard to WAG! A tattooed Emma Watson wears a pink tracksuit and UGG boots for new movie The Bling Ring

She shot to fame as teenage wizard Hermoine Granger in the Harry Potter film series.

But Emma Watson has embraced an entirely new look for her upcoming movie The Bling Ring.

The 22-year-old actress shared a picture of herself in character as Nicki on the set of the film. However, Emma looked more like a WAG than a wizard in her costume - posing up in a pink tracksuit and UGG boots.

Emma, who is sporting longer brown hair for the role, teamed her outfit with three tattoos - one on her left forearm, one on her right upper arm, and one on her hip.

Bye bye Hermione! Emma's new look is a long way from her Harry Potter role as Hermione Granger

Emma captioned the picture: 'Twitterers meet Nicki, Nicki meet twitterers : ) @blingringmovie.'

But as well as her differing style in the Jennifer Lopez style casual outfit, what was also noticeably from Emma's Twitter picture was her shrinking frame - as the actress looked tiny in the shot.

Emma has been working hard on the set of the new movie, which also stars Kirsten Dunst and Leslie Mann in Los Angeles recently.

The movie tells the story of The Bling Ring - a group of mostly teenagers based around Calabasas, California who burglarized the homes of several stars, including Paris Hilton, Orlando Bloom, Megan Fox, Rachel Bilson, Ashley Tisdale and Lindsay Lohan.

Emma's character Nicki has an ex-Playboy model mother, played by Leslie Mann, who schools her two daughters on the importance of finding fame.

Meanwhile, it was reported yesterday that Emma is in talks for a cameo role in Seth Rogen and Evan Goldberg's End of the World. 

Emma has reportedly entered negotiations to play herself in the comedy movie, with Jason Segel and David Krumholtz also set to make guest appearances in the star-studded project, which has the alternative title The Apocalypse. 

James Franco, Jonah Hill, Danny McBride and Craig Robinson are also playing themselves in the motion picture, which will see them trapped in James' Los Angeles apartment after an apocalypse breaks out.

The movie – which is currently being filmed and is expected to be released in 2013 - has been inspired by Seth and Jay Baruchel's 2007 short film, Jay and Seth vs. The Apocalypse, which features the pair starring as themselves.
