Ya know something wild would happen at the first of four Taylor Swift concerts in Los Angeles.
That something wild came in the form of a 17-year-old pop star: Justin Bieber popped up during Taylor's sold-out show at Staples Center, and the two sang his smash hit "Baby.”
“You think you’ve heard LOUD screaming in your life,” Taylor tweeted . “Then @justinbieber comes out and does a surprise song during your show. Woah. Unreal.”
Justin apparently had fun. He tweeted , “@taylorswift13 we should do that more often. :) great show! #muchlove.”
