The 'This Is Us' star and his wife are now a family of five after welcoming their second child, a baby boy with a distinctive name.

Milo Ventimiglia and his wife, Jarah Mariano, have expanded their family. The couple announced the arrival of their second child together on July 6. Mariano shared the happy news on Instagram, introducing their newborn son to the world.

The 42-year-old model posted a series of photos, including a touching black-and-white image. The photo showed her hand, Ventimiglia's hand, and their 18-month-old daughter Ke'ala Coral's hand gently holding onto the baby's tiny fingers. A second snapshot captured a warm family moment in the backyard. Mariano cradled the new baby while Ventimiglia played with Ke'ala. Their dog, Duke, sat nearby, completing the family portrait .

The couple revealed their son's unique name: Rock-Anthony Makoa Ventimiglia. While the specific meaning behind the name was not detailed, the proud mother offered a glimpse into their new life.

"These last couple of weeks have been chaos, but in the best possible way," Mariano wrote. "Welcome back home Rock-Anthony Makoa Ventimiglia. Can't wait for all of the adventures ahead with our family of 5!" .

The new arrival comes a year and a half after the couple welcomed their first child. Ke'ala Coral was born in January 2025. This birth came shortly after Ventimiglia and Mariano were forced to evacuate their home due to the devastating Los Angeles wildfires .

Earlier this year, during Ke'ala's first birthday celebration, the couple revealed they were expecting their second child. Mariano shared a photo on social media showing her baby bump. She described motherhood as the most "unique" love she has ever experienced .

Ventimiglia, 48, has spoken about how fatherhood has deepened his emotional range. The actor noted that it has enhanced his acting performances and his experiences in family life . The couple married privately in September 2023 .

The arrival of baby Rock-Anthony Makoa marks a joyful new chapter. The couple looks forward to their growing adventures as a family of five.
