Taking to Instagram on Thursday (01.10.26), they revealed they are set to give their 17-month-old son Archer a sibling in March.
They shared a series of cute family shots, including one of the tot touching Katie’s blossoming bump, and another of the couple proudly showing off their baby scan, alongside the caption: “Archer is getting promoted to big brother. March 2027.”
Fans flooded the post’s comments section with congratulatory messages, as one penned: “Ahhhh! I’m so happy for you guys. I hope you have a smooth pregnancy, labor, and delivery! This is amazing. (sic)”
A second supporter typed: “These babies are so lucky to have you guys as parents.”
And a third follower wrote: “Omg congrats to you both I’m so happy that you’re going to have another baby. May God bless this beautiful miracle love you both @jessemccartney and @katie.laura.mccartney (sic).”
Last year, the Beautiful Soul singer and the actress revealed they had welcomed Archer two months earlier than expected.
Their bundle of joy was born on May 7, but he was not due until August 8.
In a joint post on Instagram on June 17, the couple announced alongside a series of pictures of baby Archer: “Archer James McCartney took center stage on 5/7/25.
“Our sweet Archie couldn’t wait to meet us and arrived a bit earlier than expected. We are so in love with him. He loves when mommy reads him a book and when daddy sings him off to sleep.
“We look forward to bringing him home very soon to meet his big sister Bailey [their dog], who sleeps with his blanket every night. Enjoy some cute pictures of our little fighter, Archer.”
Jesse and Katie, both 39, announced they were expecting their first child together on Valentine’s Day 2024.
The pair tied the knot in October 2021, after almost a decade of dating.
Asked what attracted her to the Alvin and the Chipmunks alum, Katie previously gushed to PEOPLE: “For somebody who’s so busy and always on the go, he just has this generous way of prioritising me.
“We just make each other laugh. I feel the most comfortable being myself when I’m with him, which I think is really the true tell of when you found your person.”
