Katie Holmes jacket white pants black heels premiere

Last night Katie Holmes attended the NYC premiere of The Decision, which is a short film about ... a movie star cheating on her hairstylist?!

Holmes teamed up with John Frieda Precision Foam Colour to play Joan Hudson, an A-list starlet who decides to start doing her own dye jobs after breaking things off with her colorist. “I love the idea of doing a short film about something I feel is really important to women!” Katie said. “I also love being a part of promoting a product that is available to all women.”
