Whoa mama!

Kim Kardashian's latest sexy selfie features her growing pregnancy boobs front and center. The racy photo gives fans a very close-up view of the Keeping Up With the Kardashians star's cleavage and there's no way around it, Kim's breasts are giant!

In addition to her big boobs, the 34-year-old models a bronze bikini top that can barely contain her bosom. The sizzling snapshot was taken during her recently family vacation to St. Barts.

As for a caption to the sexy pic, Kim simply added two milk bottles, which of course is a joke about breastfeeding in her near future.
