Whoops!
Taylor Swift suffered a wardrobe malfunction while performing in front of fans Saturday night in St. Louis.
The country singer was performing her hit "You Belong With Me" when her blue halter dress blew up. Watch the eyebrow- and skirt-raising moment below!
Fortunately, fleshed-colored undergarments helped preserve the 21-year-old's modesty. She "swift"-ly held down her skirt and later fished out one piece that was still stuck ... all while singing.
She's a pro!
