Natalie Portman is busy promoting "The Other Boleyn Girl," in which she plays the upwardly mobile Anne Boleyn who steps on sister Mary Boleyn (Scarlett Johansson) to get Henry VIII. Portman sat down for a lengthy profile with the UK Times.

She defended the bosom of her friend and costar:

Back when Portman was 14, she was the face of Isaac Mizrahi, who would go on to cause a minor scandal at the Golden Globes two years ago, when he grabbed Johansson's breasts. "Seriously, I would want to grab them. She's got beautiful ones, but, Isaac, that was not so appropriate."

She also talked about their Jewish faith:

I identify very strongly as Jewish, but I could be Indian, Puerto Rican . . . Anything that gives you a cultural identity makes you know who you are and grounds you, even as a young girl trying on identities."...

And, of course, while Portman is famously Jewish, Johansson is a lesser-known Jew (because of her Scandinavian father, she's called "the kosher Danish"). When Penelope Cruz and Salma Hayek made a movie together, all the headlines blared "the Hot Tamales". What should the media label a film starring two Jewish girls? Portman doesn't miss a beat.

"The Hot Knishes," she says, referring to the Jewish delicacy.

Her feelings on spelling errors:

"I would much rather read a book or write a letter than watch television or send an e-mail. And I value good spelling. Spelling errors are a total pet peeve, which is embarrassing."

And Britney Spears:

"We both had the same first job. We both understudied for an off-Broadway musical called Ruthless. I never met her, but I took over from her when she left to join the Mickey Mouse Club. So we connected over that. She invited me to a few things and my guy friends at college said, 'We have to go.' I'm sad to see how everyone's treating her now...

Any time I see something about Britney, I close it. I can't look at it. I'm usually interested in gossip, but this makes my stomach hurt."

"The Other Boleyn Girl" opens Friday February 29.
