After making a surprise collaboration with fellow young singer Justin Bieber, Taylor Swift teamed up with Jason Mraz for another special treat on her tour. The blond beauty and the reggae pop/rock artist joined forces in one of her favorite songs "I'm Yours".
Swift wore a violet halterneck dress, and Mr. AZ went casual in a plaid shirt, denims and fedora. He strummed his guitar and kicked in the song, while she sat on a stool and followed his lead. At one point during the live duet, she encouraged the crowd for a sing-along.
Swift brought Mraz to the stage when she performed at Los Angeles' Staples Center. "I couldn't love LA crowds more. I can't believe how awesome tonight was. And thank you @jason_mraz for singing 'I'm Yours' with me!!" she tweeted on August 25.
