It's being billed as an accident, (or is it a wardrobe malfunction?) but it could also be called an ironic way to promote a clothing line by accidentally removing said clothing. It all happened last week when Beyonce took to the stage at a launch party for her clothing line at the Dereon in Toronto, Canada, according to Contact Music.

Hundreds of fans were on hand to witness Beyonce perform and during an a dance routine her blouse reportedly lifted up and exposed her bare breasts to the audience. Video of the mishaps is now making the rounds on the web. -
