Somewhere in the audience, Selena Gomez was feeling so proud of her beau and bestie!
Last night, the crowd gathered at the Staples Center was surprised with a real treat from Taylor Swift. Swifty's been performing her version of the Justin Bieber's hit Baby all tour, a very simple, classic rendition of the song. However, last night she turned it up a notch when Justin himself joined her on stage to DUET on the song!
New harmonies! New breaks! New lyrics! AAAAH-MAZING!!!
Check out the video to see Swifty and Biebs break it down for their thousands and thousands of fans! (above)
Do it again tonight! DO IT AGAIN TONIGHT!!!
