"Just some candid photos of our Super Bowl crowd today," Christine, 51, wrote in the caption of her post, which contained a picture of her with David, 59, and one of her posing alongside Mykelti and one of her grandkids. " I can’t believe it’s been a year since David and I hosted last years party. I’m definitely #teamdavid #superbowl #funtimes #hosting #family"

The vibe of the party was casual as Truely attempted as many funny photobombs as she could, kids ran around and bowls of candy and snack food were left on random tables for guests to enjoy as they lounged around in comfy outfits.

"Wow! Really captures the natural love," Mykelti wrote in the comments.

Christine and David have been celebrating many milestones since they got married in October 2023 — though the Sister Wives star still has one big item left on her checklist.

"I like the idea of having the last name Woolley," she told PEOPLE in a recent joint interview with her new husband. "I haven't done it yet because I have to change my passport, too, and we're in the middle of traveling."

She explained, "It's just a matter of timing and that's the only reason why it hasn't been done. I don't know, but I like the idea of just being a Woolley."

For his part, David's not bothered about the paperwork, telling PEOLE: "I know who she is. I'm not insecure. ... She's my wife."
