Happy Birthday to one of the greatest humans ever, my husband, best friend and the best daddy ever! We are so grateful you are ours! We Love Youuuuuu” Brittany, 29, wrote in a festive post on Instagram Tuesday, Sept. 17.
Along with her well wishes, the mother of two — who is expecting their third baby, a girl — shared a colorful carousel of photos marking the occasion.

In the first two images, the high school sweethearts posed amid a bouquet of black, red and chrome balloons at Patrick’s pre-birthday bash, which was held on Sunday, Sept. 15.

Brittany, who rested her hand on her growing bump, wore a black and white striped dress and white sneakers, while the birthday boy sported a Louis Vuitton t-shirt, khakis and matching kicks.

Sterling Skye, 3½, and Patrick “Bronze” Lavon Mahomes III, 21 months, made cameos in the other snaps, where they appeared alongside their parents in various settings — on the Kansas City Chiefs sidelines, at training camp, on vacation and at home, snuggling on the couch.
