malibu 4th of july Catherine Zeta-Jones Michael Douglas party Michael Douglas and his wife Catherine Zeta-Jones celebrated the Fourth of July with friends at a private Malibu estate, and we couldn't quite pinpoint what looked different about the Basic Instinct star until we realized he's a redhead!

The 67-year-old actor looks years younger with his new 'do, but vanity wasn't the reason for his hair color change! Catherine's hubby is returning to the big screen in the star-studded drama Last Vegas. The film co-stars Morgan Freeman, Robert De Niro and Christopher Walken, and is centered on aging retirees that throw a bachelor party in Las Vegas for the only one of them who has remained single.

Sounds like The Hangover for seniors!
