Blake Lively's On-Set Wardrobe Malfunction (VIDEO)

She may rule the Upper East Side, but Blake Lively definitely doesn't rule the weather. While on-set filming "Gossip Girl," Lively had a bit of a run-in with a gust of wind that left her exposing her bum.

The nosey gust flipped up Lively's mini skirt to reveal a pair of flesh colored underwear. But legs for days Lively shouldn't be embarrassed but rather proud of her perfectly toned assets.

No wonder this blonde bombshell scored one of Hollywood'd hottest leading men -- Leonardo DiCaprio. The pair first got cozy at the Cannes Film Festival earlier this summer and are still going strong.
