Jonah Hill’s girlfriend Olivia Millar has welcomed child as she has flat belly in Malibu

Jonah Hill is a dad!

DailyMail.com can exclusively reveal that the actor has welcomed his first child with fashion designer Olivia Millar – who stepped out in Malibu on Thursday showing off her flat post-pregnancy tummy.

This is the first child for the happy couple.

Hill’s publicist shared with DalyMail.com that the baby arrived this spring.

The last time Millar was photographed was at the end of April in shared photos by DailyMail.com. Olivia had a big baby bump as she headed out to dinner with the Wolf Of Wall Street actor in Santa Monica, Calif.

This is the first time Millar has been seen in public since that dinner.

On Thursday, the partners walked side by side in a parking lot looking at each other. They were buying takeout from Lucky’s restaurant in the celebrity-favorite coastal town.

Millar looked slim in his eye-catching sweater which appeared oversized. She added light gray sweatpants and blue and white Adidas slides with a fresh pink pedicure.

Her brown hair was slicked back and pulled back, showing off her makeup-free face. She added thin sunglasses with a light brown tint.

Jonah wore a casual outfit which consisted of a pale blue shirt worn as a jacket over a white t-shirt with straight-legged black pants with a fringed hem.

He added chunky pale blue socks to match his jacket and light blue Vans without laces. The Moneyball actor added a tan cap with blue accents to his slightly long, curly highlighted hair.

As usual, Jonas wore a bushy beard. He added a pair of aviator sunglasses while carrying his car keys and Lucky’s white take-out bag.

Lucky’s Malibu is located in the upscale Malibu Country Mart on Cross Creek Road. The restaurant offers salads, Matzo Ball soup, sandwiches, tacos, smoked salmon and omelettes.

In late April, Jonah’s daughter looked pregnant while at Katsuya’s celebrity hotspot. They joined her parents Richard Feldstein and Sharon Lyn Chalkin.

New mom fun! In late April, Olivia was photographed with a big baby bump as she headed out to dinner with the Wolf Of Wall Street actor in Santa Monica, California. This is the first time Millar has been seen in public since that dinner party.

Olivia flaunted her burgeoning baby bump in a flowing beige skirt and artistic sweater, while Hill sported a comfy brown look adorned with a cartoon image.

The couple were first linked in August 2022.

Engagement rumors have been swirling since Olivia was spotted sporting a chunky square-cut diamond ring on her finger in April.

Not much is known about the brunette mom-to-be aside from her work co-founding the online vintage site Chasseresse with her big sister Raychel Roberts.

On Thursday, her wedding finger was covered by her sweater.

The supermodel’s daughter Esme Marshall showed off her bump and ring for the first time in March when she went shopping at RealReal in Santa Monica, not far from Hill’s $6.7 million mansion.

The couple has kept their relationship private and has not made any red carpet appearances together or confirmed their relationship on social media.

Jonah was first photographed passionately kissing Millar in Malibu in August 2022.

Before Olivia, Hill dated surfer and law student Sarah Brady in 2021. The Winning Time director also dated Brooke Glazer, Erin Galpern and Isabelle McNally.

He ended his one-year engagement with KITH NYC Senior Stylist/Producer Gianna Santos in 2020.
