Pamela Anderson Graces 13th Playboy CoverTwenty years after her first appearance in the magazine, Pamela Anderson will appear on the cover of Playboy's January issue, her 13th such honor for the publication.

Us Weekly
reports that in the magazine's cozy confines, the 43-year-old Anderson gets political and slams "All the negative ads run by our politicians." The philanthropic Playmate suggests that instead, they "put that money to good use."

The mother of two, who became Playboy's Playmate of the Month for the first time in February 1990, is doing just that with the money she earned from the shoot. Anderson donated the $25,000 she was paid for her pictorial to Waves For Water, a non-profit organization that provides water filters to communities in need of clean drinking water.

Anderson told TMZ, "Waves 4 Water are my heroes. They get things done ... and yes, Playboy wrote them a check when I shot the cover directly for 25Gs."
