If you’ve ever watched the TV show “3rd Rock from the Sun” I’ll bet you’re a fan of Kristen Johnston. She won two Emmys for her role as cosmic alien Sally Solomon. Johnston has starred in several movies including Austin Powers in Goldmember, Austin Powers: The Spy Who Shagged Me and she played Wilma Flintstone in The Flintstones in Viva Rock Vegas. Kristen currently stars in “The Exes” on TV Land. Today (9/20) is her birthday, as it is for Extreme lead guitarist Nuno Bettencourt. He co-wrote both of Extreme’s big hits, “More Than Words” and “Hole Hearted.” Both Kristen and Nuno are in their 40s. Who’s older?
