Jessica, Ashlee Simpson Celebrate Family Texmas

Sisters and their significant others head to Lone Star State for family Yuletide

It's going to be a holly-jolly hoedown holiday for Jessica and Ashlee Simpson—and their significant others.

Sources tell E! News that Jessica and Dallas Cowboys QB boyfriend Tony Romo and Ashlee and hubby Pete Wentz plan to celebrate Christmas at the Waco, Texas, home of their maternal grandmother.

"This Christmas is a big deal, and the whole family wants to be together for baby Bronx's first Christmas," a Simpson family friend tells us.

Romo is already in Texas, licking his wounds after the Cowboys' big loss to the Baltimore Ravens. The rest of the clan should be arriving soon, just in time to deck the halls.
