Beyonce suffers wardrobe malfunction

Beyonce Knowles suffered a wardrobe malfunction last week, exposing her breasts during a live performance in Canada.

The 'Crazy In Love' singer's dress lifted up during a stereotypically physical dance routine revealing her chest to hundreds of fans.

The singer attempted to hold on to her top while stepping backwards, before finishing her choreographed routine as normal.

Footage of the malfunction has already started circulating on YouTube.

This is the second on-stage accident to happen to the R'n'B star in recent months following her tumble down some stairs during a gig in Florida.
