Jessica Alba’s estranged husband, Cash Warren, confirmed he’s dating model Hana Sun Doerr with a PDA-packed night out on the town.

In photos obtained by Page Six, the movie producer, 46, wrapped his arms around Doerr, 25, and kissed her on the cheek as the pair stepped out for a dinner at upscale E. Baldi in Beverly Hills Tuesday evening.

The dad of three rocked a pair of black pants and a matching T-shirt, while his much-younger date wore a white slip dress with a leather cropped jacket and matching black boots. The duo was also spotted laughing while holding hands as another couple walked behind them.

Warren’s outing with Doerr comes just weeks after he was spotted grabbing a late dinner with the model — who bears a striking resemblance to Alba — in Los Angeles on Aug. 7.
