Kim Kardashian's Bust Goes From 36D To 36G!

Kim looked sleepy as she made her way into a Los Angeles fitness studio on Friday and appeared to be wearing fake eye lashes to boot.

According to new reports, the Keeping Up With The Kardashians star has already grown four cup sizes during her pregnancy, going from a 36D to 36G.

She is said to be wearing a sports bra daily, although she appeared to have outgrown the one she had on today.

A source told Britain's Heat magazine: 'Kim loves her curves, but she's upset that nothing in her wardrobe fits her any more.'
