Meghan McCain's 'Naked' Skin Cancer Prevention PSA (VIDEO)

Meghan McCain is helping to raise awareness of the dangers of skin cancer by taking part in a new public service announcement.

The newly-released "Naked" spot comes as part of a skin cancer prevention campaign from the Style Network. The writer and daughter of Arizona Senator John McCain (R-Ariz.) is featured in the clip alongside recognizable faces such as Brandy, Tatyana Ali, who played Ashley Banks on "The Fresh Prince of Bel Air" and Danielle Fishel, who played Topanga on "Boy Meets World."

The message conveyed in the PSA is clear and simple: "If you leave the house without sunscreen, you might as well be naked."

McCain took to Twitter on Tuesday to respond to media reaction generated by the ad.

"Pundits in DC can calm themselves. I filmed a skin cancer PSA in a strapless juicy tube dress. All you can see is my collar bone," she wrote. "Both my parents have had skin cancer, everyone should be aware of the extreme dangers the sun presents and how simply using sunscreen is ... a simple way to prevent skin cancer from occurring. I take it very seriously which is why I participated in the PSA."
