EWWW! NOBODY WANTS TO SEE KOURTNEY'S PREGNANT ASS IN LINGERIE! THAT'S JUST NASTY! SCOTT SHOULD SMACK THE SH!T OUT OF HER FOR THAT!

The Kardashian sisters aren't afraid to show some skin, even if they're very pregnant.

In the new promo poster for "Keeping Up with the Kardashians," the three brunettes all appear in provocative poses wearing some barely-there lacy lingerie.

Kourtney Kardashian — who is due to give birth any day now — is no exception. The mom-to-be sports a black lacy baby doll dress, reports PopEater.com.

The tagline at the top of the poster reads: "What a difference a year makes." When the show returns to E! this season, Khloe Kardashian is married to basketball superstar Lamar Odom, Kim Kardashian has become a spokeswoman for a diet supplement, shedding some serious pounds along the way, and Kourtney is just about to give birth to her first baby by boyfriend Scott Disick.

The newest season of "Keeping Up with the Kardashians" premieres on Sunday, Dec. 13 at 10 p.m. on E!
