Knowles blames live mix up on jet lag

R&B superstar Beyonce Knowles has blamed her hectic work schedule for her slip up at last week's 'BBC Chart show live' event, when she mistakenly thought she was in the British capital instead of seaside resort Brighton.

Knowles, 24, upset local residents when she expressed her delight at being "back in London" - but quickly apologised when she was informed of her mistake.
