Where You’ve Seen Her: You may remember Kaley as the ditzy daughter on 8 Simple Rules, but little Bridget Hennessy is all grown up. She’s been hard at work over the years, appearing on shows such as Charmed and Prison Break, and in films including Killer Movie and The Last Ride. Oh, and let's not forget about her stunning Maxim cover. Now, this blonde bombshell is famous for schooling a bunch of nerdy neighbors in the lessons of life on the Thursday night CBS hit The Big Bang Theory, which kicked off its seventh season last week.
