Tulisa Contostavlos Shooting Her New Solo In Grandma's Bikini

 Over the past few weeks, Tulisa Contostavlos has been hitting the beaches and pools of Miami and Los Angeles in a series of tiny bikinis. But as she prepared to shoot the video for her debut solo single in Florida today, the N-Dubz singer, 23, decided to look to the '50s for inspiration.

The X Factor judge showed off her curves in a floral Ted Baker 'Pictou' swimsuit, exaggerating her slim waist with a elasticated red belt. Despite her wide grin on Miami Beach today, Tulisa may have been struggling after a late night partying with her entourage and rapper friend Chipmunk. She wrote on Twitter this morning: 'I feel like death warmed up, but its all good #Videoshoot.' As ever, Tulisa was accompanied by her PA and best friend Gareth Varey, who apparently has his own assistant on the video shoot.
