Christmas is just a few days away, meaning families will be gathering for their holiday traditions, and that includes Britney Spears.

"We always do a tree, we do dinner, a huge dinner, we do presents and we are all about Santa," Britney recently told MTV News.

According to Britney's younger sister, Jamie Lynn, who recently stopped by MTV News to perform her debut country single, "How Could I Want More," it looks like the Spears family is taking those traditions on the road. They'll spend their holiday in Sin City, where, two days after Christmas, Britney will kick off her two-year residency, "Piece of Me" at Planet Hollywood Resort & Casino.

"We are actually going to go to Vegas and the whole family is going to be there," Jamie Lynn said before adding that she will not be making an appearance onstage during her sister's show. "I'm just there to be a cheerleader and that's kind of intimidating. I don't know how to dance."

Joining in on the Christmas Day festivities will be Jamie Lynn's 5-year-old daughter Maddie and Britney's two sons Jayden James and Sean Preston. Jamie Lynn revealed that she's become very close with her nephews over the years.

"It's really cool. They are two boys, and it's weird because I feel like she's tougher than them," she said. "It's really cool to see their dynamic. She keeps right up with them."

And speaking of tough, let's hope there are no arguments between Britney and Jamie Lynn, who recently collaborated on Britney's eighth album Britney Jean, this holiday season. The two both have admitted that they rarely fight. But when they do, things get a little physical.

"Sometimes we get on each other's nerves, and we will actually physically wrestle," Jamie Lynn said. "And she really thinks she can beat me every single time and she never does. I don't know why she keeps trying. My dad loves it. He doesn't stop it either; he just let's it go and walks in the other room. He probably can't hear; he has hearing aids."
