Are you getting into the holiday spirit? Carrie Underwood sure is! The superstar singer has her very own two-hour variety show, Carrie Underwood: An All-Star Holiday Special, airing tonight on FOX! But she won't be singing just holiday songs -- she's going to sing songs from her brand new album, Play On and old faves, plus she'll be performing with some special guests too, including David Cook, Dolly Parton, Christina Applegate, and Kristin Chenoweth. "It's just a big mish-mash of awesome music!" Carrie says.

Carrie is also performing with her CMA co-host Brad Paisely, but that one will be a bit different from the rest. "He couldn't actually be in L.A. for the taping, so we did something kind of cool to bring two locations together," Carrie reveals. But look for her duet with her fellow Idol alum David Cook to be a highlight of the special. "We rocked out for a minute and got to sing together again," she says. "It was probably one of my favorite moments of the show because I just love him to death."

And Carrie is psyched to continue celebrating the holidays off-air too! She loves playing her fave Christmas songs, "Oh Holy Night" and "Little Drummer Boy" to get into the spirit. "Growing up we don't have too many traditions as a family, but we would always celebrate Christmas on Christmas Eve and Santa would come on Christmas morning," Carrie says. "[This year] I'll just be with my family. We don't really have that many traditions, but we are together, and that's the most important thing. We eat ourselves silly!"

Carrie Underwood: An All-Star Holiday Special airs on Monday, December 7 at 8 p.m. ET/PT on Fox.
