Actor Channing Tatum is staying fit this holiday season by challenging his wife Jenna Dewan-Tatum to a Christmas Day dance-off.

Tatum met the 32 year old on the set of their hit 2006 street dance movie Step Up, and now they are both putting their skills to the test during an ultimate round of Xbox video game Dance Central 3.

She tells People.com, "We'll be playing the Xbox Kinect 4 Dance Central 3. We get very competitive when it comes to video games, but this one in particular we're going to have a lot of fun with. I'm hoping that I will be able to say I kicked his butt, but we'll see."

And the actress, who recently announced she is expecting their first child, reveals her husband's relatives from Cullman, Alabama may even join in the fun.

She adds, "Last year we were with my side of the family, so this year we'll be with his side in the South."
