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.
