“Kim loves her curves,” a source told the mag. “But she’s upset that nothing in her wardrobe fits her any more.”

Apparently, the star has gone up a whopping FOUR cup sizes!

The reality star has reportedly gone from a 36D to a 36G since announcing her pregnancy. Very busty, we must say.

No wonder the star is keen to hit the gym.
