Lea Thompson — in 1988 and 2012
Lea Thompson made girl-next-door adorableness an artform. Those dimples, the big brown eyes, that wholesome smile — there was nothing about the young Lea that wasn't completley loveable. She racked up girl crushes as Lorraine McFly in the Back to the Future franchise and as Caroline in '90s sitcom Caroline in the City. The 51-year old actress still epitomizes effortless American charm — these days she plays mother Kathryn Kennish on ABC Family's Switched at Birth. We love you, Lea!
