Katy Perry perform in 'BBC Teen Awards': Katy Perry and Taylor Swift took the stage and rocked the BBC Radio 1's Teen Awards in London this weekend. Looking cuter than ever, Katy Perry rocked a tight white bubble gum machine inspired dress with fun booties that resembled candy canes. The quirky starlet sang "Teenage Dream" until she dropped to her knees in an entertaining performance.

Taylor Swift looked classically glam as usual. The country star sang her hits "Love Story," "Speak Now," and "Mine." The crowd loved Taylor as she wooed them with her angelic vocals.
