Jenna Dewan-Tatum Debuts Newly Blond Hair—Hot or Not?

Channing Tatum's wife says her lighter locks are "just for a role"

So, do blondes really have more fun?

Jenna Dewan-Tatum posed that question Monday. The actress posted a picture to her WhoSay page showing off her newly lightened locks. "About to find out :)" she wrote.

But Channing Tatum's wife isn't playing with peroxide just for fun. "Oh, and the new hair is just for a role guys...started a new movie today:)," she clarified on Twitter Tuesday.

Jenna's gorgeous as a brunette, but we're liking the platinum tresses! Somehow we think though this lady would look lovely with any hairdo.
