A Jonas Brothers concert in Connecticut almost turned X-rated for young fans after hearthrob Joe Jonas suffered a wardrobe malfunction onstage. The 20 year old was left red-faced when a button holding his pants together popped out midway through the band's performance at the Mohegan Sun Casino on October 9.

Things went from bad to worse when his fly unraveled, forcing him to hold his trousers up with one hand and croon into his mic with the other.

A stagehand eventually spared his blushes by handing him a clip to keep his costume intact.

A source tells Star magazine, "He scurried over to the side of the stage and someone handed him a paperclip. He looped in through the buttonhole and stitched up the fly onstage while (band mates and brothers) Nick and Kevin distracted the crowd."
