EXCLUSIVE LEONA Lewis celebrated her birthday by dancing the night away with Simon Cowell, Louis Walsh, a morbidly obese clown and a strongman… well, nearly. The X Factor winner headed to London’s A-List haunt, Cirque le Soir for her 29th birthday, and was greeted at the door by another of Cowell’s proteges – Chrissy Darling, from Britain’s Got Talent stars Club Town Freaks, whose entire outfit was themed around the singer’s biggest hit, Bleeding Love.
