Patrick Mahomes and Brittany Mahomes’ daughter Golden is officially one!

On Monday, Jan. 12, Brittany, 30, celebrated their youngest’s milestone birthday by sharing a sweet montage video of her party on Instagram.

Golden was all smiles as she marked her special day surrounded by family and friends, with the little one donning orange flower sunglasses at one point to go with her yellow dress, and a tiny “One” crown in other parts of the clip.

Golden’s siblings, Sterling Skye, 4, and Patrick “Bronze” Lavon Mahomes III, 3, were also seen in the video eating cotton candy, as well as playing on a slide, on the bouncy castle and in the ball pit, with the party appearing to have a flower theme.

The clip — that had BØRNS’ “Electric Love” playing in the background — also saw Golden enjoying a cake that had pink icing and strawberries around it, as well as playing with her dad, Patrick.

“Celebrated our Golden girl with the best crew,” Brittany captioned the post, adding a yellow heart and sunshine emoji.

Brittany also celebrated the special occasion on her Instagram Stories, posting a cute boomerang showing the mother and daughter posing together.

“My baby is ONE,” the former soccer player wrote, adding a teary-eyed and crying emoji.

“This baby girl is pure joy,” Brittany wrote over another Instagram Stories post that featured three shots from Golden’s birthday bash. She tagged Patrick and added a stars and a sunshine emoji.

Brittany’s birthday posts for Golden come after the Mahomes celebrated their first Christmas as a family of five.

The Kansas City Current co-owner shared a series of family photos to Instagram on Thursday, Dec. 25, featuring them posing in matching pajamas, opening gifts, the kids posing with Santa Claus, and more. She also showed Golden posing with a little Santa hat on her head, as well as wearing some very cute bows.

“Merry Christmas,” Brittany captioned the photos, adding a Christmas tree and red heart emoji.

The final picture in the carousel of images showed Patrick sporting a knee brace as he continued to recover from his injury after suffering a torn ACL.

The injury occurred in the final two minutes of the Kansas City Chiefs’ Dec. 14 game against the Los Angeles Chargers, with the athlete being seen going down in pain, clutching his left knee.

Just one day later, Patrick underwent surgery to repair his ACL, and, according to multiple outlets, he also needed a repair for a torn LCL.

Patrick — who was also pictured in his brace celebrating New Year’s Eve with his family — has no doubt been making the most of his extra time at home, with the couple regularly sharing snapshots of their life with their kids on social media.

Despite loving being a family of five, Brittany said last year that she and Patrick have no intention to welcome another child “for a while.”

“Nope,” she said on the June 11 episode of the WHOOP podcast. “We’re done. We’re done for a while. Three. I don’t know, I mean, I feel like you can never like, say you’re done, but I think three is all I need.”
