Here are two photos of Cheryl Tiegs. One taken in her modeling heyday, and the other taken for the September issue of W Magazine. It's hard to believe Cheryl Tiegs is 58 years old in the second photo. Her 59th birthday will be on September 25th. She was born in 1947.

Cheryl Tiegs is considered to be the first ever supermodel. (Sorry, Janice Dickinson.) When she was 17 she had already been on the cover of Glamour. She was the cover model for the Sports Illustrated Swimsuit Issue three times - in 1970, 1975 and 1983.

Tiegs has been married four times. Her last marriage ended in 2001. She gave birth to twins at the miraculous age of 52 (with the help of a surrogate mother) and has one other older child.

Now that her twins are in school she is going back to business and has partnered with Revlon for an accessory and wig line.
