Mariah Carey flaunts toned body in new Jenny ad

Mariah Carey is reveling in her weight loss as the new spokesperson for Jenny, the weight loss regime that she credits for triming 30 pounds from her frame following the birth of her twins. Carey, 41, told her fans over Twitter to check out a new promotional ad for the brand. It features her in a tiny black tube top and short black skirt with thigh-high splits. "Watch my latest Jenny commercial, set to Make It Happen C&C remix. You can make it, go," she wrote. The camera pans her body and highlights her flat stomach and toned abs. The commercial is set to her 1991 hit "Make it Happen", while Jenny dieters reveal how much weight they've lost on the program, which mainly relies on portion control. Carey gave birth to twins Moroccan Scott and Monroe after a difficult pregnancy. She suffered from post-pregnancy edema (severe water retention) and other complications including high blood pressure, preeclampsia and gestational diabetes. She said she started using the Jenny diet plan in July and has lost a total of 70 pounds. "I'm proud of how hard I worked to get my body back," she said on OWN's Rosie Show. "I had to do this for me." The New Ad Can Be Seen HERE (Celebrity Health & Fitness)
