The busty star accompanied the image with the message: 'Happy Birthday to my hubby @NickCannon..."my baby I'm waiting on youuuu"hahaha KKLB! GHL!!!! Mwah!!!!'
The comedian and actor Cannon, who is Mariah's second husband, was celebrating his 33rd birthday this week, but it might not be a raucous affair, with Mariah still recovering from a dislocated shoulder and broken rib from a recent music video.
Joking about her accident, Mariah, 43, explained that whilst being directed by her husband on the video shoot, which was a remix of her track Beautiful, she was so tired she collapsed whilst trying to pose.
'About the ninth take, tenth take, I was on a roll darling, a roll! And the next thing I knew I was on the floor, baby...on cement.'
The pair, who have been married for five years, also have twins Monroe and Moroccan, 2, who were born via C-section in 2011.
Previously the pop star was married to Tommy Mottola, an American music executive twenty years her senior, but they divorced in 1998. We're sure he's kicking himself after this latest picture Mariah.
