Mariah Carey may be in her forty's, but the woman only seems to look better and better as the days go by.  She's always maintained a healthy yet curvy figure, and is fearless when it comes to showing off her bust to the world via Instagram.  She's posted a number of bikini pictures on the social networking site, and recently uploaded a few new ones for her fans to enjoy.

The most recent picture, is of her wearing a tanned bikini with her plump cleavage clearly showing, and the other is a "Throwback Thursday" picture of her taking a selfie while wearing a pink bikini.  Looking at the past and present pictures, you can see how well Mariah has aged both in her face and body.
