As the goody two-shoes of Hogwarts, her alter ego Hermione Granger would probably frown at the mere thought of associating with such troubled company.
But yesterday Harry Potter star Emma Watson was pictured hanging out with the 'bad girls' at Paris Fashion Week.
The 18-year-old actress was sat in the front row watching the Christian Dior Ready-to-Wear collection show, next to none other than Lily Allen, Dita Von Teese and Katy Perry.
Renowned for her outbursts, Lily hit the headlines recently after telling Elton John to 'f** off' during an on-stage rant as she co-presented the GQ Awards.
And in another far cry from Watson's clean-cut image, Dita is known for her sexy burlesque dance routines and former relationship with goth-rocker Marilyn Manson who she was married to between 2005 and 2007.
It was also notable that Watson, who is currently working on the final instalment of the Harry Potter films, sat slightly inclined away from I Kissed A Girl singer Katy Perry.
Perhaps she was avoiding the possibility of Katy planting a smacker on her cheek.
Watson is becoming a familiar face on the fashion circuit and looked stylish in a classy grey belted coat and vertiginous black lace-up boots.
She has signed up to the Storm agency which also represents Kate Moss, Carla Bruni and Lily Cole.
The young actress, said to be heading for university post-Potter, could find herself in demand as a cover girl instead.
