Britney and Jamie Lynn are sisters and bffs, but even besties throw down every once in awhile!
"Sometimes we get on each other's nerves, and we will actually physically wrestle," Jamie Lynn told MTV News about her and Britney when they're not chillin, chillin. "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."
Speaking of kicking butt, JL says daughter Maddie Briann could probably beat up Sean and Jayden.
"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."
The Spears family will get their chance to see who's tougher this Christmas in Vegas where the family will unite to spend the holiday together before Brit's Vegas residency kickoff performance.
"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."
Britney recently told MTV News: "We always do a tree, we do dinner, a huge dinner, we do presents and we are all about Santa."
