Christie Brinkley and Billy Joel divorced back in 1994 and now the supermodel is helping her ex cope with his latest breakup.

Katie Lee Joel is doing her best to move on as well. The TV chef made her first public appearance on Thursday night at the premiere of "Julie and Julia" in New York City. Katie confidently walked the red carpet -- and went stag!
