The couple first announced the news of their firstborn’s incoming arrival in February in exclusive photos with People, where the pair were seen holding their sonogram photos while frolicking on the beach.
They also uploaded their own Valentines Day themed photoshoot, wearing “mum” and “dad” monogrammed pajamas and making a heart with their hands over Peterson’s growing baby bump.
They also shared a sonogram photo surrounded by red roses and hearts reading “Baby Mac” and “Aug. 2025”, the baby’s original due date.
A month later they revealed the gender of their child in another Instagram post, with the couple planning a picnic with their dog Bailey for the occasion.

The three opened the basket in front of them to find a blue collar, which Katie slipped over the dog’s head as the Alvin and the Chipmunks star pumped his fist in the air and said, “It’s a boy! No way!”
The star then became teary-eyed as he embraced his wife.
The couple dated for seven years before getting engaged in 2019, after which they tied the knot in 2021.
