She may have gained a few pounds since her last swimsuit photoshoot, but Mariah Carey is clearly feeling confident with her hourglass curves. The 40-year-old flaunted her figure in a revealing satin swimsuit with plunging neckline as she frolicked on the beach during a video shoot yesterday. But it appeared the clingy costume didn't prove quite enough support for her famously ample cleavage.

Singing her heart out: Mariah hits those famous octaves

As she ran around the beach posing and singing for the promo, she narrowly avoided a wardrobe malfunction as her breasts came dangerous close to falling out of her skimpy beachwear. She also changed into a better-fitting white swimsuit with cut-out sides which complemented her honey tan.

Mariah was shooting the video for her third single release H.A.T.E.U, which is due for release in the new year. With her new album Memoirs Of An Imperfect Angel riding high in the charts and her personal life better than ever, Mariah is feeling more confident and happier than ever before. Speaking earlier this summer, she admitted her happy marriage to toyboy husband Nick Cannon, 29, had affected her waistline.

She said: 'I'm a curvy girl and switch around with my diets all the time.'

When she first started dating Nick in March 2008, she was slim and toned thanks to daily workout sessions in her swimming pool. But while Mariah has reassessed her priorities in recent months and focused her attention on balancing her busy working schedule with spending time with Nick.
