The couple announced the arrival of their second baby together by revealing the name of their son via a joint Instagram post on Monday.
Alongside a photo of the infant's legs in a brown and white onesie, the Kansas City Chiefs quarterback and his wife simply wrote in the caption, "Patrick 'Bronze' Lavon Mahomes III 🤴🏽11/28/22 7lbs 8oz 🤍."
A silver chain with the name "Bronze" engraved in the middle can be seen in the photo on top of a blanket that reads, "Mahomes."
The news came after Brittany, 27, shared a carousel of Instagram images on Saturday that showed her posing nude with her growing baby bump on full display.
Covered only by a white, lace sheet in the photographs, Brittany struck a variety of poses for the shoot, including one where she stood with her belly popping out from underneath the fabric, and another where she sat on the floor as she cradled the sheet over her chest.
"Can't believe I'll soon have 2 little loves🤎," Brittany captioned the post.

The proud mom also shared a carousel of images from the same photo session earlier this month, featuring Patrick, also 27, and their 20-month-old daughter, Sterling Skye.
In one snap, Brittany and Patrick could be seen cuddling up to each other while the two sat on a wooden floor and placed their hands on Brittany's baby bump. Another image showed the couple joined by Sterling, whom Brittany held in her arms while the toddler sweetly embraced her.
Brittany and Patrick announced in May that another baby was on the way and due in early 2023.
At the time, the pair posted photos on Instagram with Sterling holding a board that read, "Big sister duties coming soon," and an additional photo holding an ultrasound picture. Patrick captioned the photo, "Round 2! 🤍."
