9. Tina Turner

Tina is almost 70 years old, but she looks like she's 30. She has the body and the legs of a young woman. She's the only grandma on earth that has sexy legs like that. And what grandma do you know has the voice that Tina has? Tina showed the world that she's a gilf when she wore a tight sexy silver outfit onstage while performing with Beyonce at last year's Grammy Awards. A lot of guys went to bed that night dreaming about having a duet with Tina Turner.
