Jenna Dewan: Channing Should Have Been Vampire

Recently married actress tells us she agreed with Twilight screenwriter's idea to cast her G.I. Joe hubby in Eclipse

Twilight screenwriter Melissa Rosenberg isn't the only one who thinks hunky Channing Tatum would have been perfect to play Riley in Eclipse.

The G.I. Joe star's wife, Jenna Dewan, says director David Slade should have let hm sink his teeth into the role.

"I totally tried to get him to do it," Dewan told us earlier this week at the InStyle Summer Soirée at the London Hotel in West Hollywood. "I was like, 'Baby, do Twilight!' Oh, my god. I'm a huge Twilight fan. I've read all the books. So I was like, 'You should do it, you should do it, you should do it!'"

Unfortunately for Jenna, Xavier Samuel snagged the part of the corrupted vampire in the third installment of the Robert Pattinson bloodsucker movie franchise. 

While Dewan says Tatum hasn't read any of Stephenie Meyer's Twilight books, she's a huge fan...

"I just saw the trailer for [New Moon] today," she said. "It's one of those things where I liked the books so much, I felt like a 10-year-old reading them. I finished them in like three days."

Eclipse or no Eclipse, it seems the newlyweds are more about work right now than starting a family. Dewan is about to start shooting a two-episode stint as a film executive on the CW's new Melrose Place, while Tatum just wrapped Dear John and has at least three more flicks in the works.

"Ask me in a couple years," Jenna said about having babies. "We do want them, just not right now. If I have three, if I have 10—I just want them to be happy and healthy kids."
