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

Olivia flaunted her growing baby bump in a flowy beige skirt and artful jumper, while Hill sported a cozy maroon look with a cartoon image.

The pair were first linked in August 2022. Engagement rumors have been circulating since Olivia was spotted sporting a large square-cut diamond ring on her finger in April.

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

The daughter of supermodel Esmé Marshall first revealed her bump and ring in March while shopping at The RealReal in Santa Monica — not far from Hill’s $6.7 million mansion.

The couple kept their relationship private and did not appear on the red carpet together, nor did they confirm their relationship on social media.

Jonah wore a casual outfit that consisted of a light blue shirt worn as a jacket over a white t-shirt and dark straight-leg pants with a fringed hem.
