Holy cow!

Hugh Hefner's former girlfriends Karissa and Kristina Shannon threw on their tightest crop tops and pencil skirts to go shopping at Chanel yesterday, and let's just say they've added a few extra pounds to their already curvy frames since the last time we saw them!

It seems like they might have plunked down some cash to enhance their booties, too!

Their butts are rivaling Kim Kardashian's!

We're a little confused how they can afford to shop at the super pricey designer boutique, because last time we checked the only way they made money is by sleeping with old men like the Playboy founder!

Someone needs to tell these two to lay off the spray tans!
