American actor Jonah Hill welcomed his first baby with his partner Olivia Millar, his rep told People on Friday.
The baby's gender and name have not been revealed.
The news comes amid another big milestone in Jonah's family. His sister Beanie Feldstein married producer Bonnie-Chance Roberts on May 20 in upstate New York.
The "Don't Look Up" star was first linked to Millar —a co-founder of the online vintage clothing retailer Chasseresse—in August 2022, when the two were spotted PDA on the beach in Malibu, California.
A month after the sighting, Hill embarked on a road trip with the fashion maven and her family, including her older sister Raychel Roberts, up the coast to Santa Barbara.
The couple appeared to have taken their relationship to the next level in the new year. On January 10, Hill and Millar were seen shopping at a kids' clothing store during a trip to Hawaii.
Hill, who largely keeps his personal life private, was previously engaged to Gianna Santos. The pair called it quits in 2020 after two years together. He was next romantically linked to surfer Sarah Brady.
