Natalie Portman rang in the Jewish new year with family and friends at Serafina in White Plains on Sunday.

“It was a huge group of about 16 . . . They were celebrating Rosh Hashanah. She was with her daughter and her husband and they were taking pictures of food, laughing and having fun. She seemed very happy and doted on her daughter,” an insider told Page Six.

Portman even brought her own challah bread, honey and pomegranate to the restaurant, and the group said a prayer in Hebrew.
