Pixie Lott 20th Birthday Party at Club Movida in London

Pixie Lott and Jamelia's birthday parties came to abrupt end this morning after police evacuated part of London's West End.

The two singers' celebrations at the Movida club in Argyll Street, Soho, were cut short when a man threatened to blow himself up in a nearby shop on Regent Street in the early hours of this morning.

Pixie was marking her 20th birthday, while Jamelia was celebrating her 30th at the exclusive club. Check out 10 more images after the jump.
