Robert Plant

Just because 64-year-old Robert Plant is in senior citizen territory, doesn't mean he's too old to be coy when it comes to romance. Just last month the Led Zeppelin frontman revealed he had secretly married singer Patty Griffin, 48. "I eloped and ran off to Texas. So now I spend half my time there and half here," he told The Independent in July, referring to his wife's home in Austin, Texas, and his residence in England. He also said in the interview that he and his wife of an indeterminate amount of time live in "an old crack house in Austin" infested with termites. "I tap my hand on the table and they fly out the walls in this huge cloud, like something from a Disney film." Sounds romantic!
