Christa B. Allen will forever be known to a whole generation or two as young Jenna from 13 Going on 30. In the classic body swap/time travel movie, Jennifer Garner plays the grown up version of her after making a wish. But the OG that made us love the character first? The real thing? That was Christa. However, while she may be frozen in time in the hearts of filmgoers, her life has gone on. Heck, she's even had time to pass 30 IRL! And her real life has apparently been pretty damn dramatic lately...
