Mariah Carey decided to share a gift for Nick Cannon's 33rd birthday with the world, showing off her ample chest. Carey, who has been married to Cannon for five years, posted a cleavage-baring photo on Twitter wearing an open white blouse and racy black bra.

“Happy birthday to my Hubby @NickCannon…”my baby I’m waiting on youuuu hahaha! KKLB! GHL!!! Mwah!!!!” the photo caption said.

Carey, 43, began secretly dating in 2008 before making their relationship public. They wed within two months of their first date. They now have twins, Monroe and Moroccan.

After having the twins two years ago, Carey is showing that she is definitely back in shape.

The singer last year said on the Rosie O’Donnell talk show: "In the beginning, when I first had babies, I had so much edema. … water and swelling. Most pregnant women have that just in their feet.

"One day I was doing my thank-you notes and I noticed it started rising up the leg, so I had edema … I didn't think I would ever be the same person."

Eventually, Carey did lose the extra pounds through the Jenny Craig weight-loss program.  She is now the Grand Ambassador of the company. "The first week, I lost 40 pounds … of just water," she told O’Donnell. "When I started with the program, I lost at least 30 pounds of weight that needed to be lost." Carey added, "I would tend to go, 'Does this size dress fit me that I wore three years ago? I'm good, let's go.' I would go by what it looked like, how I felt."

It remains to be seen what Cannon’s physical gift from Carey will be, but considering how lavish Carey is, it is sure to be a grand present.
