Singer Toni Braxton was left red-faced during a concert in New Brunswick, New Jersey last week (ends16Aug13) when she suffered a wardrobe malfunction while dancing seductively with a fan.

The R&B star appeared to be unaware of the extent of the problem as she bared her backside to giggling fans, and she refused to step off the stage for a costume change when her dance partner told her that her thong was on show before offering up his sports jacket.

Braxton continued performing as an assistant and a backing singer attempted to mend the dress, and she was still singing when a stagehand removed it altogether, leaving the Un-Break My Heart hitmaker wearing nothing but high heels, a thong, a bra, her fan's jacket and a smile.

The fun-loving star gave the audience a quick flash of her underwear before continuing with her concert.

Footage of the wardrobe malfunction, captured on a camera phone, has been obtained by and posted online.
