Rita, who suffered a bittersweet ending to the show when she lost her act Lauren Murray, put on an extremely busty display in her glittering black and gold jumpsuit.

The blonde beauty wore her hair in sleek waves which were pulled from a centre parting, although the main focus was on her style credentials and the striking ensemble.

As she sported the stand-out look, the halter neckline struggled to contain her ample bosom while she greeted the adoring audiences.

She flashed even more flesh through the sheer material on the wide legged Pallazo style trousers.

Cheryl, who enjoyed a successful evening when her act Reggie N Bollie went through to the finals, battled to ensure all eyes were on her in her luminous gown which featured an ombre hemline. 

The stunning gown, which featured a polo-neck detail, clung to every inch of her superslim frame.

The fishtail ombre base of the ensemble extended into a large train which drowned the singer slightly meaning she struggled slightly to walk along and was assisted by co-judge Simon Cowell.
