Beyonce Knowles shocks all by baring breasts

Beyonce Knowles, well known simply as 'Beyonce', has bared her breasts to the delight of many male fans at a performance last week.

However, it came as a shock for a few, even though the very few who were offended still stood up to look.

'The Naughty Girl' was appearing at the launch of her clothing line Dereon in Toronto, Canada, when the mishap occurred - but footage of the exposure has been posted on the internet.

During an energetic dance routine, Knowles' top lifted up, revealing her bare breasts to hundreds of fans.

It is the latest on camera - and on-stage - embarrassment for the singer.

Last month (Jul07), footage of Knowles taking a tumble at a gig in Florida was uploaded on video-sharing site YouTube, despite pleas from the singer for fans to keep the incident private.
