VIDEO : Jenna Dewan-Tatum Joins Supergirl! Find Out Who She's Playing

Superman's younger/older cousin, meet Lois Lane's younger sister! Supergirl has tapped Jenna Dewan-Tatum to play Lucy Lane.
The younger Lane is apparently just as "brash, funny, and beautiful" as her big sister, but she's also "strong, smart, and successful" all on her own. She has a history with Jimmy Olsen (played by actors Mehcad Brooks) and she comes to town to right a previous wrong. The actress (and incredibly cool wife of the equally cool Channing Tatum) most recently starred in The Witches of East End, and also appeared in American Horror Story: Asylum, and The Playboy Club.
