Taylor Swift Duetted With Mraz During Show

Taylor Swift is turning her Los Angeles residency into a star-studded event - she duetted with Jason Mraz during her concert on Wednesday (24Aug11).

The Love Story hitmaker is playing a string of shows at the Staples Center and earlier this week (begs22Aug11) she thrilled fans by bringing Justin Bieber onstage for a rendition of his hit track Baby.

And Swift introduced another special guest to the crowd on Wednesday, teaming up with Mraz to perform his song I'm Yours.

In a post on her Twitter.com page, she writes, "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!!"
