See Heidi Klum's Fashion Week Reunion With Christian Siriano

It was a Project Runway reunion this weekend as Heidi Klum came out to support season four winner Christian Siriano and his spring 2012 collection in NYC.

Klum, who palled around with Siriano backstage, sat front row with fellow famous faces Corinne Bailey Rae,  Modern Family's Sarah Hyland and actress Monet Mazur.

So what does the designer appreciate most about his supermodel pal and mentor? "She's a tough critic...She's like, ‘I wouldn't wear that, but I would wear this.' And I think that's so real and perfect."

Total honesty from Miss Auf Wiedersehen? We wouldn't expect it any other way!
