"Supergirl" Casts its Lucy Lane

"Supergirl" now has its Lucy Lane: As reported by TVLine, Jenna Dewan Tatum has joined the cast of the DC Comics-based CBS series as Lois Lane's sister, described as "brash, funny and successful in her own right" -- and an ex-girlfriend of Jimmy Olsen (series regular Mehcad Brooks). It's slated as a recurring role.

Though not as iconic as Lois, Lucy Lane is a long-running character in her own right, created by comics legends Otto Binder and Curt Swan and first seen in 1959's "Superman's Pal Jimmy Olsen" #36. In 2009, the character briefly took on the "Superwoman" identity. Lucy Lane is frequently depicted with a romantic connection to Jimmy Olsen, a tradition the show looks to be continuing.

Dewan Tatum has appeared in films including the original "Step Up" and "The Grudge 2," and was seen on TV in recent years in "American Horror Story: Asylum" and "The Mindy Project." It's been a big few days of comic book-based news for the Dewan Tatum family -- this past weekend, it was reported that her husband Channing Tatum had finalized a deal to star in 20th Century Fox's "Gambit" film.

"Supergirl" is scheduled to debut Oct. 26 on CBS.
