justin bieber taylor swift gi Surprise! Justin Bieber and Taylor Swift duet at her Los Angeles show“You think you’ve heard LOUD screaming in your life,” Taylor Swift tweeted after her Los Angeles show on Tuesday night. “Then [Justin Bieber] comes out and does a surprise song during your show. Woah. Unreal.”

Yes, Bieber made a surprise appearance during the Swifty concert. These two have been longtime friends (even moreso now that he’s dating her BFF, Selena Gomez) so while we’re sure fans were shocked, it can’t have come as that much of a surprise.

“We should do that more often. 🙂 great show! #muchlove,” Bieber tweeted to Swift.

The pop favorites sang a duet on Bieber’s song “Baby.” Bieb’s manager, Scooter Braun, was sitting on the secret beforehand. “Had to keep it a secret all day. But [Bieber] just came out and sang BABY with [Swift] at STAPLES. EPIC ROAR! #greatmoment,” he tweeted.
