"He's a nice Jewish man from a nice Jewish family," Barrymore said of Kopelman, a 35-year-old art consultant.
"I'm a shiksa [gentile]. I do the seders and we do Passover. I haven't converted yet, but Olive will be raised traditionally," the actress said during an appearance on TV show The View.
The couple married in a very traditional ceremony about eight months ago.
Barrymore called Judaism "a beautiful faith" and said she's "so honored" to be around it. "It's so family-oriented. The stories are so beautiful and it's incredibly enlightening. I'm really happy."
The actress credits her daughter for making her a better person.
"(Olive) actually has made me a morning person, so she's already made me a better person in every way possible. I'm like Godzilla in the morning... Before I've had that cup of caffeine. And with her, I sing her 'Good Morning' with my husband from Singing in the Rain every day. She has the biggest smile and it's the first time I've smiled in the morning. I love it!," Barrymore said.
