The Czech-born model, 56, announced on Instagram Tuesday that she and the famed director, 60, have broken up.
“I’m so grateful for his presence in my life. He helped heal me and reclaim myself. There truly may be no better man, no man who’s more genuinely ‘good.’ He’s brilliant and witty and funny and sexy,” she captioned the post.
Page Six broke the news in April that the former Sports Illustrated Swimsuit Issue stunner and the screenwriter were dating. Two days later, the pair made their debut at the 2021 Oscars, where they walked the red carpet together.
Porizkova was previously been married to Cars lead singer Ric Ocasek after meeting him when she was only 19.
They tied the knot in 1989 when she was 24 and he was 45 and went on to have two sons — Jonathan, 27, and Oliver, 23 — before announcing they had amicably separated in 2017. Ocasek died two years later at age 75.
Sorkin, meanwhile, was previously married to Julia Bingham — with whom he shares daughter Roxie, 20 — before they divorced in 2005. The New York City native was then variously linked to Kristin Chenoweth and Kristin Davis.
