Heidi’s sporting a new do, and now reminds us a little of Princes Leia – but we’re sure that’s just because of the outfit – while Renee has been taking hair-advice from Tom Cruise we’re sure.

Hayden went for the chop as well, making her look older and much more serious. We’re not exactly sure if that’s a good thing, but it seems like that’s what she was going for. Do you have the courage to say goodbye to your locks and follow his trend?
