During a performance of her song You Belong With Me, the Grammy winner's blue dress blew up thanks to fierce gust from the wind machine.
It was eerily reminiscent of the famous scene in 1955's Seven Year Itch, in which the skirt of Marilyn Monroe's white halter neck dress is lifted by a violent breeze from a passing train as she stands on a subway grate. And though Swift revealed her less than pretty seamless panties, the practical nude coloured garment spared her blushes. She patted down her skirt as quickly and firmly as possible, and simply got on with performing her show - to cheers from the audience.
Unlike many of her contemporaries, the country sensation is modest when it comes to flaunting her enviable figure.
In April she told The Telegraph that she "[doesn't] feel comfortable taking [her] clothes off."
"I wouldn't wear tiny amounts of clothing in my life, so I don't think it's necessary to wear that stuff in photo shoots," she added.
Taylor was honoured for her contributions to entertainment with the Ultimate Choice Award, the show's version of a lifetime achievement award. Accepting her Ultimate Teen Choice surfboard on stage, Swift thanked her fans and joked: "It's been a long time since I was a teenager, like two years."
