Billionaire Merivale Owner Justin Hemmes, 52, and Model Madeline Holtznagel, 28, Welcome First Child
Justin Hemmes Welcomes First Child with Partner Madeline Holtznagel
Justin Hemmes, the 52-year-old billionaire owner of Merivale, and his partner, model Madeline Holtznagel, 28, have welcomed their first child together—a son named Jaeger Justin Hemmes. Madeline announced the arrival on Instagram Sunday, sharing heartwarming photos of their newborn.
The post featured snaps of baby Jaeger swaddled in blankets, Madeline glowing in a pink pajama set while cradling him, and the couple enjoying a windswept beach walk with their son tucked into Justin’s jumper. Friends and family flooded the comments with congratulations, including Madeline’s sister, model Simone Holtznagel, who wrote, “I love him,” and The Bachelor star Anna Heinrich, who called the baby “beautiful.”

This is Justin’s third child—he shares daughters Alexa, 9, and Saachi, 7, with ex-partner Kate Fowler. Madeline, a first-time mom, told Stellar magazine she always envisioned being a “boy mom” and is excited for Justin to have a “little best mate.” She added, “Justin has two beautiful girls, so this is a whole new journey together.”

The couple kept the pregnancy private initially, with Madeline explaining, “I don’t share a lot online, but now it’s nice to celebrate this chapter.” She leaned on her sisters, Anna and Simone—who welcomed her own daughter, Gia, in 2024—for parenting advice.
Rumors of Madeline’s pregnancy surfaced in late 2023 when a friend moved out of Justin’s $100 million Vaucluse mansion to make space for their growing family. The pair, who began dating in 2019, have faced engagement speculation after Madeline was spotted wearing a ring on her wedding finger during a Japan trip, though they’ve yet to confirm plans to marry.

Justin, with a net worth of $1.39 billion, has built a life blending family and business. Madeline, meanwhile, balances motherhood with her modeling career and close-knit family ties. As they embrace life with Jaeger, the couple appears focused on cherishing their “new journey” together.
