Taylor Swift flashes butt onstage

Taylor Swift suffered an embarrassing wardrobe malfunction during a gig over the weekend (13-14Aug11) when her dress blew up to reveal her butt.

The country singer was performing in St. Louis, Missouri on Saturday (13Aug11) wearing a blue halterneck frock as she sang track You Belong With Me.

But Taylor Swift was left red-faced when a gust of wind blew the back of the dress up to reveal a pair of large, skin-colored underpants. The hem of the dress was then stuck revealing the back of her thigh.

The resilient 21 year old refused to let the exposure ruin her performance, and continued to perform the song to the adoring crowd.
