Recently, Project Runway winner Christian Siriano made big news when he let loose a little Hills dis. The sassy seamstress voiced some distaste with Heidi Montag and Lauren Conrad’s clothing collections, thus causing quite a stir amongst the religious celebrity right. Christian dropped by the office yesterday to meet about hosting MTV.com’s Red Carpet Fashion Review at this summer’s MTV Movie Awards, and I was able to pull him aside for some pointed questions (specifically, what will he say to LC and Heidi when he sees them there?). Watch the video to hear him elaborate on his prior Hills infraction, and swing back here tomorrow for a our Hills fashion exclusive, in which Christian (aka. Ferocia Coutura) critiques the cast’s individual style. Hint: Brody Jenner gets rave reviews.
