Actress Alicia Silverstone has jumped on the non-circumcision bandwagon, her new book reveals.

Beyond the Bris, a website that opposes circumcision, quotes Silverstone's explanation for sparing her son the snip in "The Kind Mama: A Simple Guide to Supercharged Fertility, a Radiant Pregnancy, a Sweeter Birth, and a Healthier, More Beautiful Beginning."

“I was raised Jewish, so the second my parents found out that they had a male grandchild, they wanted to know when we'd be having a bris (the Jewish circumcision ceremony traditionally performed eight days after a baby is born),” writes Silverstone, who started in the 1995 movie hit "Clueless."

“When I said we weren't having one, my dad got a bit worked up," she writes. "But my thinking was: If little boys were supposed to have their penises ‘fixed,’ did that mean we were saying that God made the body imperfect?”

Silverstone has long been open about her Jewish identity. In a profile on the website interfaithfamily.com, Silverstone said in 2000 that she grew up in California attending a Reform Temple.

"I was reared in a traditional Jewish household," Silverstone recalled in the interview. "We lit candles Friday night and had seders. My brother David and I went to Hebrew school and had our bar mitzvahs. I have wonderful memories of my bat mitzvah."
