Britney Spears rocks out in London's West End

Britney Spears took a break from rocking the stage on Tuesday night to sit in the audience of the Rock Of Ages musical in London's West End.

The Toxic hitmaker is currently in the U.K. on her Femme Fatale tour, and she couldn't resist heading to the U.K. capital's famous theatre district to watch the rock-themed production at the Shaftesbury Theatre.

Britney Spears took in the show with her boyfriend Jason Trawick, before heading backstage to meet the cast, which includes British pop star Shayne Ward.

Ward took to his Twitter.com after the meeting, writing, "Met Britney Spears tonight. She was kind enough to come backstage and have a picture with us all. She was lovely and looks really well."
