Bristol Palin shoots PSA warning against teen pregnancy

Bristol Palin, daughter of former Alaska Gov. Sarah Palin, is continuing her campaign against teen pregnancy.
The Candie's Foundation just released a public service announcement featuring Bristol, warning that if it weren't for her fame, family, and opportunities, her life as a teen mom of son Tripp would be much less glamorous.  Watch:

  Bristol, of course, is nationally known because her pregnancy became public immediately after John McCain selected her mother as his GOP running mate in the 2008 presidential campaign. Since the Palin choice was targeted at socially conservative "movement" voters, her daughter's status as an unmarried and pregnant 17-year-old created a minor furor at the time. Bristol has remained in the public eye since, with appearances on magazine covers and TV shows, and also thanks to her later split with the child's father, Levi Johnston. Johnston's repeated media appearances discussing Bristol and her mother have been ready fodder for the gossip circuit.
Bristol Palin's anti-pregnancy campaigning also comes after she initially called efforts to promote abstinence to teens "not realistic."  She's since reversed her position and worked with the Candie's Foundation, her mother, and others encouraging teenagers to abstain.
