Lisa Rinna and Harry Hamlin

It's quite the achievement when couples are able to preserve a happy marriage for multiple decades, it's even more of a success when that marriage is faced with the pressures of living in the public eye as a pair. Harry and Lisa have been married since 1997. They've appeared as Logan's parents on Veronica Mars and they play themselves on The Real Housewives of Beverly Hills. Rinna commented on their happy union, "I think you either really dig somebody, or you don't." Insiders report that Harry watches every episode of The Real Housewives of Beverly Hills because he's such a supportive spouse.
