Katy Perry suffers wardrobe malfunction in 'American Idol' twerk battle

Katy Perry isn't afraid to give it her all on the dance floor, even if it means an accidental wardrobe malfunction!

The American Idol judge laughed it off like a pro on an episode that aired Monday night in the US. Fellow judges Lionel Richie and country music star Luke Bryan were dancing along with Venezuelan contestant Michelle Sussett, who beckoned the 33-year-old 'Swish Swish' singer to join in.

Her co-judges swooped in to help her up, Bryan lifting her arms and Ritchie blocking her body so she could pull down her dress.

"Is everything covered?" Ritchie quipped.

"There are some things a man can't unsee," joked Bryan.

But Perry wasn't flustered by the misstep. In fact, she cooly replied, "I'm the best dancer ever."
