SugarlandJennifer Nettles and Kristian Bush may have agreed on which songs to put on Sugarland's new Christmas album, 'Gold and Green,' but when it comes to decorating for the holidays, they completely disagree.

"I kind of dig Christmas lights," Kristian tells GAC. "If I could decorate an entire room in just the Christmas lights, it would be a little bit like college, but like a grown-up version of that."

Jennifer, however, takes an entirely different approach. "I don't mind the white lights," she says. "Those are good for all occasions in any sort of decorating. But I like to keep it for the season. It feels more special to me that way."

The Grammy-nominated duo will experience plenty of Christmas lights -- and a whole lot of star power -- on Dec. 20, when they join an all-star cast including Mary J. Blige, Neil Diamond, Rob Thomas and Usher for 'Christmas in Washington.' Hosted by actor and comedian George Lopez, the special will air on TNT at 8:00 PM ET.
