Gwyneth Paltrow once said that she didn't "believe in religion" but in a complete u-turn, she now claims she will be raising daughter Apple, 7, and son Moses, 5, in a Jewish environment.
The American actress discovered her family came from a long line of influential East European rabbis in ancestry programme Who Do You Think You Are? earlier on this year.
Gwyneth's late father, Bruce Paltrow, was a Jewish film producer and her actress mum, Blythe Danner, is a Christian. "It was such a nice way to grow up," Gwyneth said about her parent's different religious beliefs.
Husband and Coldplay singer Chris Martin also has a Christian background.
Gwyneth recently spoke at an event in London hosted by Jewish charity the Community Security Trust. This was where she told guests the news, according to the Daily Mail.
"Miss Paltrow may just want to follow traditions that she did as a child, like observing the Sabbath, keeping a kosher home and celebrating holidays," a genealogy expert told the newspaper.
