She is well-known for playing notoriously chaste Bella Swan in the Twilight films.

No more Bella: The Sopranos' James Gandolfini watches Kristen strip
Wearing a see-through mesh bra with red tape on her breasts, fish-net stockings and heels, she is a world away from her clean-cut teenage role opposite real-life boyfriend Robert Pattinson in Twilight.
During the scene, well-meaning James tries to refuse her advances, asking her age, while she swears at him, accusing him of being a cop.
The new film is an emotionally-intense drama about a couple, played by James and Melissa Leo, who lose their daughter in a car accident and become close to Kristen's character, trying to save her.
At a recent New York screening of the movie, Kristen explained she had to take pole dancing lessons for her role.
Bruised: Kristen Stewart was offered a job as a stripper as she researched her new film Welcome to the Riley's
'I did two weeks of it. … I did learn how to do it and I got bruises all over my legs. It’s hard, but it actually doesn’t look painful, but it is.
It kinda beats you up,' she told Entertainment Tonight.
'This is something that any girl can relate to: If you love yourself and you respect yourself, that’s the only way anybody else is going to,' Kristen said.
It seems Kristen was excellent at dancing, as she claims she was offered a job as a stripper while she was researching the part.
She had visited a strip club with the director to prepare for her role as 16 year-old Mallory.

She said: 'I went to a strip club with the director and the costume designer and it being an odd grouping of people going into a strip club in the middle of the afternoon, I was, like, straight-up offered a job.'
The star also said she was left covered in bruises while rehearsing for her role.
'I pole-danced for two weeks,' she said. 'I had bruises all over my legs… it hurts!,' she said.
The indie flick, Welcome To The Riley's is in limited cinemas across the UK.
Meanwhile, Kristen, and Robert Pattinson are currently shooting the last in the Twilight franchise, Breaking Dawn parts one and two in Rio de Janeiro.
