STAIR MASTERS

The Kardashian-Jenner clan reached new heights with their glamorous 2010 Christmas card, which featured Kourtney's boyfriend Scott Disick and baby Mason Dash for the first time. "Our card this year might be my favorite," Khloe wrote on her blog. "Mason is in it, which makes it even more special. Look at him standing there in his pinstripe suit."
