Taylor Swift's Top Falls Off Onstage!

When you think of a wardrobe malfunction, the last person on your mind is Taylor Swift. After all, the squeaky clean 22-year-old songstress, who spends her off-time knitting and baking with friends, doesn't really wear anything remotely revealing, onstage or off. But alas, Taylor has suffered the same fate as Janet Jackson and Katy Perry - to an extent!

On September 22nd, while playing at the iHeartRadio Music Festival in Las Vegas, Taylor's strap came undone from her sparkly 20s-style dress and fell off, exposing...another top! Luckily T-Swift was wearing a glittery long sleeve top underneath her dress, and was able to finish up her performance of "Sparks Fly." Before going on to perform the next song, "You Belong With Me," she made the switch and decided to wear the black shorts she had on for backup with the undershirt. Such a pro, that Taylor!
