Whoa ... TMI!

Kourtney, Kim And Khloe Kardashian are never one to keep a secret, and in a playful game of "Would You Rather" for Glamour magazine, the girls are dishing on sexy bedroom habits.

The three sexy sisters are featured on the cover of Glamour's New Year's Special issue.

These photos of the ladies wearing their bedroom gear were definitely shot before Kourtney's baby bump started showing.

We have a feeling that post-baby, Kourt will have no problem getting her body back in shape!
