Today is the birthday of someone with a VERY famous mom. In fact, she could run for President some day. Sarah Palin’s daughter Bristol Sheeran Marie Palin made headlines in 2008 when she gave birth to Tripp Easton Mitchell Johnston. She wasn’t married. Bristol is now a teen pregnancy prevention spokesperson. She has competed twice on Dancing With The Stars and was just eliminated from the current edition of the show. Today is also the birthday of actor Zac Efron. He has starred in the films Hairspray and High School Musical, as well as the TV series “Summerland.” Both Bristol and Zac are in their 20s. Who’s older?
