They’ve performed at the venue a dozen times so JLS’ Oritsé Williams thought it would be just any other gig.

But the singer was soon in for a shock when he realised his bandmates had secretly hired a buxom stripper to come on stage during their G-A-Y set to mark his birthday.

His pals, Aston Merrygold, Marvin Humes and Jonathan ‘JB’ Gill grinned with delight when their surprise pulled off and a stripper turned up to help celebrate him turning a quarter of a century old.

Oritse burst out laughing when the scantily clad woman named Gloria walked on stage dressed in stockings and leotard, with pink studded heels, a white shirt and pearl necklace.He was in for more shock as she ditched her shirt and later bared her breasts.

After straddling the singer and squirting his face with cream, she then presented him with a large birthday cake.Oritse blew the candles out and then seemed happy to bury his head in her chest – much to the delight of his bandmates.
