Jenny McCarthy is 39 and fine!
The sexy mother of one's Playboy cover debuted this morning -- showing her in the buff almost 20 years after her first appearance in the magazine.
This is Jenny's fourth pictorial for the mag: she first appeared in it back in 1993 and was named Playmate of the Year in 1994 (left).
While it may be a racy spread for a mom, Jenny says she's "really proud of it."
"The pictures are really gorgeous and classy. They could be out of W magazine," she tells PEOPLE. They're really elegant. It's probably a lot more sophisticated than a lot of the stuff you'd see of people with their clothes on."
There's no denying McCarthy looks great on the cover -- but how have some of the other Playboy models from the '90s held up over time?
