The reality star has launched her own bootcamp, and has promoted it by baring her bum in a bid to sign people up.
Dressed in a flesh-flashing black leotard and a pair of heels as she carries a pair of dumbbells, the Essex girl shows off her derrière in the promo shots.
Lucy Mecklenburgh has launched a 'booty' camp
“I’ve created Booty Camp because I genuinely love being fit and healthy and I want to show people how easy it is," Lucy said in a statement.
“It’s such a shame when people say they’re scared of working out and find it too hard because with my plan it couldn’t be easier. I genuinely hated exercise before I started on this mission. Now I couldn’t live without it.
“I’m looking forward to welcoming people from all over to BootyCamp. We promise you an amazing weekend where you’ll leave fitter, slimmer, healthier and beat the post Christmas bloat! Let me help you kick your butt into shape!” she added.

Lucy has previously defended herself against critics who said she was too skinny, after losing weight in the wake of her split from Mario Falcone.
She told Heat magazine: "I don’t like the skinny-skinny look. I don’t think I’m too thin. My personal trainer wouldn’t let me get too thin, and neither would my family.
"I’m feeling good. I’ve worked hard for it. I always eat healthily, and I use a personal trainer two to three times a week.
"I’d never let myself go below 8st. I’m 8st 4lb now. This is my ideal weight," she added.
