Jonah Hill steps out with pregnant girlfriend Olivia Millar for dinner with his parents

Jonah Hill stepped out with his pregnant girlfriend Olivia Millar in Santa Monica on Wednesday for a casual dinner.

The 39-year-old You People star — who recently transformed into his alter ego for a Lakers game with Lisa Rinna — took his rumored fiancée to celebrity hot spot Katsuya, where they joined his parents Richard Feldstein and Sharon Lyn Chalkin.

Olivia showed off her burgeoning baby bump in a billowing beige skirt and artsy sweater, while Hill sported a cozy maroon look with a cartoon graphic.

The couple were first linked in August 2022 and are currently expecting their first child together.

Engagement rumors have been swirling about the parents-to-be as Olivia has been spotted wearing a large square-cut diamond ring on her finger in recent weeks.

Not much is known about the brunette mom-to-be apart from her work as a co-founder of the online vintage site Chasseresse with her big sister Raychel Roberts.

The daughter of top model Esmé Marshall first revealed her belly and ring last month when she went shopping at The RealReal in Santa Monica — not far from Hill’s $6.7 million mansion.

DailyMail.com has reached out to representatives for Hill, who was not available for comment until now.

The pair have kept their relationship private and have not appeared on the red carpet together nor have they confirmed their relationship on social media.

Jonah was first photographed passionately kissing Millar in Malibu on Aug. 28. In September 2022, the duo also spent time together in Santa Barbara on a road trip together.

Before Olivia, Hill dated surfer and law student Sarah Brady in 2021.

The Winning Time director has also dated Brooke Glazer, Erin Galpern and Isabelle McNally.

He ended his yearlong engagement to KITH NYC lead stylist/producer Gianna Santos in 2020.

Hill opened up about struggling with his weight since childhood in the Netflix documentary Stutz last year, telling how his mother negatively impacted his relationships with women by insisting he lose weight as a teenager.
