Justin Bieber's Surprise Duet with Taylor Swift
Taylor Swift has been covering Justin Bieber's "Baby" during her latest concert tour, but last night in L.A., she did one better!

Instead of just singing his song, Swift was able to get Bieber himself to come out and duet with her on stage -- sending the crowd into hysterics.
The show was Swift's first of four sold out concerts at the Staples Center ... no word on if Bieber (or maybe someone else) will pop up on stage tonight.
Check out the duet, shot by a fan, above!

Two worst/weakest/over-rated live vocals in the current music scene. Alas, when can we hear real singers live? Beaver can't hit high notes any more and Swift always has pitch issues proven live in Award shows.

Swift is FABULOUS live. I've been to her Speak Now tour. I understand what you mean -- in award shows, she has issues sometimes, but that is not at all typical of her vocals live. You obviously did no research in making that comment.

I'd have to agree with with johnson on this, they both sux and taylor's mom an dad have money. An they used that to say hey I'll pay you this much to make her voice sound good on cd's.
