Demi Lovato stops to sign a few autographs for fans as she leaves BBC Radio One studios in London on Sunday night (April 26).

The 16-year-old actress/singer wore a pretty Petites Rose Print Prom Dress, a recent purchase from Miss Selfridge.

After she left BBC, Demi tweeted, “I’ve never heard Girls Aloud but I have somehow ended up at their concert! Should be fun. Back at the hotel. Those girls were sooo pretty. Not fair. Haha about to take a bubble bath and relax from this CRAZY week!”
