Harry Potter star Emma Watson seen with bad boy rocker

"Harry Potter" star Emma Watson worked some magic on the red carpet, showing up to a celebrity-studded London party in a sleek, low-cut dress, high-heeled pumps and an interesting fashion accessory on her arm: controversial rock 'n' roller Johnny Borrell.

The 17-year-old Watson, who boasts a squeaky clean reputation that mirrors her Hermione character from the "Harry Potter" movies, looked a tad more wicked showing up for the Vanity Fair and Burberry Portraits viewing party with Borrell, who is ten years her senior.

The singer and guitarist for the band Razorlight has been linked to other, older, starlets like Kirsten Dunst. Borrell also has a reputation for tooting his own horn more than playing his guitar.

"I feel like a genius more than most people, that's for sure," Borrell once told NME Magazine.

Watson, on the other hand, was often ridiculed on the set of the "Harry Potter" movies for her straight-A grades. She's managed thus far to juggle her studies with her skyrocketing film career.

Perhaps, opposites really do attract.
