In the new drama My Generation, Jaime King faces a major acting challenge: portraying her character at both 18 and 28. Jaime plays Jackie Vachs in the mockumentary series, which follows a fictional class's senior year and catches up with them again a decade later. In high school, Jackie is the quintessential popular cheerleader with dreams of super stardom, but when we meet her again at 28, she’s not exactly where she expected to be. The actress recently sat down with us at PopSugar Studios to talk cheering, Jackie's hidden past, and why she thinks the show is the most groundbreaking new show of the Fall. You can catch My Generation on Thursdays at 8 p.m. on ABC.
