Actress Nina Dobrev has stripped down to help promote U.S. leader President Barack Obama's signature healthcare law.

The Canada-born Vampire Diaries star has posted a topless picture of herself holding up a sign that reads "getcovered" on Instagram.com.

She writes, "I'm Canadian. We have healthcare for all. If you dont (sic) have insurance go to and GetCovered (sic),Because w/o (without) it, youre (sic) naked".

Dobrev is not the only celebrity raising awareness for Obama's Affordable Care Act, which went into effect on Tuesday (01Oct13) - Pearl Jam star Eddie Vedder and his bandmates took to Twitter.com shortly after the launch and declared, "If you want to make sense of the whole healthcare thing, or just want to GetCovered (sic), check out... KnowYourOptions (sic)".
