Freeze Out! Kardashian Clan Continues To Ignore Rob's Engagement During Family Ski Trip

During a recent taping of KUWTK, Kim Kardashian and hubby Kanye West took baby North on her very first snowmobile ride in snowy Colorado.  

Kourtney took on the pistes in a fierce-looking black and brown choice of skiing attire with stylish colored sunglasses.  

Khloe was less lucky than her fashionable sibling, as she later burst out of her outfit.  

Their family trip comes on the heels of brother Rob's engagement to hot and heavy girlfriend Blac Chyna.  

Though the Kardashian sisters' disapproval of Rob's new squeeze is no secret — they haven't even commented on the big news! — momager Kris Jenner didn't waist any time to turn her son's life-changing decision into a major payday!  

“Kris has done a total U-turn on this romance now that it’s a possibility she could profit from it,” a source told RadarOnline.
