Mariah Carey Almost Busts Out Of Cleavage-Baring Dress

It wouldn't be Mariah Carey if she wasn't wearing a cleavage-baring dress!

The "Elusive Chanteuse" shared a steamy Instagram selfie on Wednesday which showed her in the back seat of a plush car wearing a body-hugging gown that threatened to let loose her girls, which were practically busting out.

Mimi's intended audience (aside from her 1.6 million Instagram fans)? None other than David Letterman, who had the 44-year-old as his special guest.

When the mom-of-two got out of the car, we got to see the gown in all its glory: a shimmery fishtail dress with a lace hem that she accessorized with a black lace glove on one hand, movie star sunnies and lots of diamond jewelry, including a butterfly ring that replaced her wedding bling (giving more fuel to the divorce rumours).

Of course, the Wonderland cover girl didn't show any signs of possible trouble in paradise with hubby Nick Cannon. Instead, the glamorous vixen smiled broadly and blew kisses to her fans.

She truly is a superstar.

Mariah's always had a flair for the dramatic:
