Almost two decades after Jenny McCarthy was named Playboy's Playmate of the Year, she's stripping down and baring all again for the July/August issue of the nudie mag.

The 39-year-old host of the NBC summer series 'Love in the Wild' first posed for Playboy in 1993, later going on to receive the Playmate of the Year honors and parlay her fame into a successful television and film acting career.

But even though she looks slammin' now, the model and actress ballooned during her 2002 pregnancy, saying she once tipped the scales at 211 pounds. Thanks to an endorsement deal with Weight Watchers, she shed the excess poundage and returned to a slim 120 pounds, crediting the diet program for teaching her "portion control and to be conscious" of what she ate.

In recent years, though, she's become more known for her outspoken criticism of children's vaccines than her appearance, saying in her book 'Louder than Words: A Mother's Journey in Healing Autism' that she believes such vaccines can lead to autism -- a claim debunked by many medical professionals.

'Love in the Wild,' which will have McCarthy "guiding contestants through rigorous adventures as well as the choppy waters of relationships in their quest to find love," debuts on NBC on June 7th. Perfect timing for a little publicity bump in Playboy.
