The high school sweethearts are currently expecting their third 𝑏𝑎𝑏𝑦

Patrick Mahomes is celebrating his wife on her special day!

As Brittany Mahomes turns 29 on Saturday, Aug. 31, her husband and high school sweetheart dedicated a special Instagram post to her to mark the milestone.

The Kansas City Chiefs quarterback, who turns 29 next month, kicked off his 𝐛𝐢𝐫𝐭𝐡day tribute to Brittany with a picture of the longtime couple with their two kids, daughter Sterling Skye, 3, and son Patrick “Bronze” Lavon Mahomes III, 1.

In the sweet family photo, Patrick grabs onto Sterling’s hand and Brittany, who is currently pregnant with the couple’s third 𝑏𝑎𝑏𝑦, holds hands with Bronze.

For the next slide, Patrick picked a photo of the couple celebrating one of the accomplishments Brittany achieved this year — her Sports Illustrated Swimsuit debut in February.

The NFL star selected a picture of the couple smiling as they celebrated the Kansas City Current co-owner becoming a member of SI Swim’s 2024 Rookie class at the magazine’s 60th anniversary issue party in May.

The quarterback let the photos speak mostly for themselves, leaving a simple message for Brittany in the caption. “My ❤️!” he wrote. “Happy 𝐛𝐢𝐫𝐭𝐡day! @brittanylynne.”

Brittany shared the tribute — and specifically the family photo — on her own Instagram Stories, where she wrote, “My everything🥹🤍.”

The soon-to-be mom of three also shared some behind-the-scenes pictures of her 29th 𝐛𝐢𝐫𝐭𝐡day celebration.

On Friday, Aug. 30, she documented her pre-𝐛𝐢𝐫𝐭𝐡day dinner with several photos, starting with a shot of two friends, which she captioned, “Birthday dinner with my girlies.”

Also joining the group of pals was her football star beau, she revealed in another post, adding, “And my lover @patrickmahomes.”

Brittany also showed a table decorated with flowers and candles in her posts, as well as her 𝐛𝐢𝐫𝐭𝐡day cake — a white confection covered in purple and gold leaf — and tons of sparklers.
