The Instagram Announcement

According to reports from People, Just Jared, and E! News, the couple shared the news on October 1, 2026, with a series of sunlit backyard photos. Coordinated in white outfits, the pair posed with Archer — dressed in a tiny bowtie and clutching a strip of sonogram images — to share that their family is growing. The joint Instagram caption read: "Archer is getting promoted to big brother 🤍 March 2027".

Archer's Sweet Moments So Far

Archer, born in May 2025, has already had his share of adorable public moments. In January 2026, McCartney shared a video of the baby at the piano, calling him his "new co-writer." During a New York City show, the singer wrapped Archer in a blanket embroidered with "Beautiful Soul," and the family dressed up as puffins for Halloween.

Who Is Jesse McCartney?

McCartney first found fame in the boy band Dream Street before launching a solo career with his 2004 breakout "Beautiful Soul," a Billboard Hot 100 hit. His 2008 single "Leavin'" climbed to No. 10 on the Hot 100 — his biggest hit to date. He also co-wrote Leona Lewis' Grammy-nominated, US chart-topping "Bleeding Love." With five solo studio albums and more than 25 film and 30 television acting credits — including Alvin and the Chipmunks, All My Children, Greek, and the final season of Hacks — he remains a multi-hyphenate star.
