Find out who she's playing on CBS' 'Supergirl.'

Looks like the Tatum family has caught the superhero bug!

Just days after Channing Tatum closed his deal to play Gambit on the big screen, his wife Jenna Dewan Tatum is suiting up as her very own heroine on the small screen.

The 34-year-old actress is joining CBS’ anticipated rookie drama, Supergirl, as Lois Lane’s older sister Lucy Lane, ETonline confirms.

In Supergirl, Lucy is described as “as brash, funny and beautiful” and is “strong, smart and successful in her own right.” When Lucy comes to National City, she’s there with the hopes of righting a previous wrong. Complicating matters, however, is the fact that she’s got a deep history with Jimmy Olsen (Mehcad Brooks).

Uh oh, should we be expecting a love triangle between Lucy, Jimmy and Kara? Or rather, a love rhombus, if you throw in Kara's nerdy friend Winn Schott (Jeremy Jordan)?

This actually won’t be the first time the character of Lucy Lane has appeared on TV. Back in the Smallville days (remember that WB staple?) The Flash’s Peyton List played the role!

Honestly, we’re super excited about the former Witches of East End’s introduction to the Supergirl universe. Maybe then we could get a Gambit-Supergirl crossover. Just think of the possibilities...

Dewan Tatum is just the latest star heading to Supergirl, joining Twilight’s Peter Facinelli, who will be playing a tech billionaire obsessed with the city’s newest heroine.

Supergirl herself, Melissa Benoist, recently spoke to ETonline about bringing the female superhero to life.

“It’s a daunting feeling in the best way because obviously it feels like a responsibility but I love that I can do it in this way -- that she’s quirky and kind of weird and flawed and funny in a way that Kara [Zor-El] is discovering herself right now when we meet her in the pilot,” Benoist told ETonline at Comic-Con. “I’m glad I can show girls that you can do anything that you want to do.”

premieres Oct. 26 at 8:30 p.m. ET/PT on CBS.
