Kelly McKee Zajfen is celebrating the arrival of the newest member of her family.

The Alliance of Moms co-founder, who is a close friend of Meghan Markle, announced that she had welcomed a baby boy via Instagram on Thursday, March 26. The baby’s arrival came just one day after her own birthday on March 25.

“The best birthday gift ever. 🎉 Happiest birthday to you sweet Jack Oliver Zajfen,” she wrote below the carousel of photos taken at the hospital.

“(Jack: In honor of my Gandpa. Oliver: in honor of our Georgie. Now they share the same middle name),” she continued, explaining her new baby’s name.

“This family of 5 is madly in love. Full of all the emotions and taking it all in. Thank you all for being apart of this journey and loving our family. I have felt carried and loved so very much and that’s what Community is all about. ❤️‍🩹,” McKee Zajfen wrote, and joked, “Get ready for a lot of baby content 🙃💝”

The snaps included a photo of Georgie’s twin sister, Lily, now 13, holding her little brother.

The comments section of her post was flooded with well-wishes, including congratulations from the Duchess of Sussex’s friend and makeup artist, Daniel Martin, the Highbrow Hippie haircare brand and atelier credited for Meghan and McKee Zajfen’s tresses at a recent event, Amanda Kloots and more friends.

The news comes four years after McKee Zajfen and her husband, Julian, lost their son George to COVID-19 and viral meningitis at age 9.

McKee Zajfen announced her pregnancy in November 2025. In an Instagram post at the time, she wrote, “Sometimes… just sometimes… when you let light in through the broken pieces of your heart, love grows. 🌱 Baby boy coming this Spring. 💐”

She added, “The path here wasn’t easy, and yet love kept showing up in the smallest signs, the quietest moments, the light that refused to fade. This little soul is already so loved, a reminder that joy and grief can exist together… and that hope has a way of finding us again.”

In April 2024, McKee Zajfen wrote a personal essay for PEOPLE, opening up about George’s death and sharing how friends like Meghan had helped her through it.

“Please allow others to show up for you in whatever way they can,” she wrote. “I have learned to delegate my grief. I know certain people who can hold space and support in the heavier days. Or who I can share in the ridiculous moments that come.”

“I have learned that not one single human can carry it all for us, so allowing others in is imperative,” she continued. “Try not to expect people to understand it all. Even the people who share a similar loss. Not everyone will understand. That is the lonely part, I am afraid. So be brave in sharing.”

McKee Zajfen and Meghan, 44, recently stepped out together to attend the Alliance for Children’s Rights 34th Annual Champions for Children event in Beverly Hills, California, just last week on March 19.

There, Meghan presented her friend with the Francis M. Wheat Community Service Award, recognizing her commitment to the Los Angeles community as the co-founder of the Alliance of Moms and board member of the Alliance for Children’s Rights.

McKee Zafjen and Meghan have been friends for almost 20 years. In 2024, Meghan and Prince Harry attended the George Zajfen Tennis Tournament in Los Angeles, an event that honored McKee Zafjen’s late son and benefited the Alliance for Children’s Rights. The couple also donated $5,000 to a GoFundMe set up in George’s honor in the names of their two children, Prince Archie and Princess Lilibet.

After the tennis tournament, McKee Zajfen posted a photo with Meghan and Harry on Instagram and praised them with a caption that said, “Harry and Meghan, you have been such a guiding light for our family, not just in the way you have shown up in friendship but how you have shown up through the incredible work The Archewell Foundation does every day. I’m in awe of your commitment to community and to friendship.”
