(CNN) - Meghan McCain's taking it all off in a new ad.
The outspoken daughter of former Republican presidential candidate, Sen. John McCain is appearing in a new public service announcement on the Style Network to warn against the dangers of skin exposure.
McCain appears alongside recognizable faces like musician Brandy and actresses Tatyana Ali and Danielle Fishel, among others, seemingly naked to promote the message that "If you leave the house without sunscreen, you might as well be naked."
The Arizona senator's eldest, writer daughter responded to criticism via Twitter Wednesday.
"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 of my parents have had skin cancer, everyone should be aware of the extreme dangers the sun presents."
