R&B singer Brandy and actress Tatyana Ali have bared all for a new health campaign raising awareness about the dangers of skin cancer.
 
The stars, along with former "Boy Meets World" star Danielle Fishel, are among a group of female celebrities who have disrobed to appear in a new public service announcement urging people to use sunscreen on a daily basis.
 
The advertisement, titled "Naked," will air in time for summer.
