IT LOOKS as if

Natalie Portman

may get more out of "Black Swan" than an Oscar nomination.

The petite star has gotten engaged to the film's choreographer, Benjamin Millepied, and is pregnant with their first child.

A publicist for Portman, 29, confirmed yeterday that the couple are engaged and expecting, but declined to give any further details. People magazine first reported the news.

The pair met during the making of director Darren Aronofsky's psychological, toe-shoe thriller. Millepied also played a small on-screen role in the film as a dancer.

* It's a boy for Alanis Morissette and Mario "Souleye" Treadway.

A rep for Alanis, 36, said in an e-mail yesterday that Ever Imre Morissette-Treadway was born Dec. 25. The e-mail says that "all are healthy and happy."

Opening up leaks

Wikileaks founder Julian Assange says that he's being forced into penning an autobiography to keep his organization from going under.

That's right. He's being forced.

And New York publishing house Alfred A. Knopf confirmed yesterday that it had struck a deal with the Australian secrets-outer to release his autobiography, publication date to be determined.

Assange, speaking to London's Sunday Times, said that the deal would bring in more than $1 million, with $800,000 from Knopf and another $500,000 from U.K. publisher Canongate. But he said that he agreed to it only because he was under financial pressure.

"I don't want to write this book, but I have to," he said. "I have already spent 200,000 pounds for legal costs and I need to defend myself and to keep WikiLeaks afloat."

Knopf spokesman Paul Bogaards declined to comment on the specific figures mentioned by Assange, but confirmed that a deal had been in place since "prior to the holidays."

Bogaards said that Assange was due to deliver his manuscript sometime in 2011. The autobiography's title hasn't been made public.

How about "Something Wiki This Way Comes"?

Tattbits

* The East Coast blizzard hasn't dimmed the lights on Broadway.

Paul Libin, chairman of The Broadway League, said yesterday that the Great White Way was open for business as usual, with shows going on as scheduled. He added that cancellations could mean that hard-to-get seats may be available.

Gee, maybe the Eagles and Vikings could catch a show. It really is a sad day when bad weather cancels a football game before it cancels "Mamma Mia."

* According to TMZ.com, Kelsey Grammer has asked a California judge to put a rush order on his divorce from Camille Grammer so that he can marry his new fiancee, Kayte Walsh.

That seems like bad Grammer.

* An 18-year-old woman has been charged with breaking into the Atlanta mansion of Tyler Perry.

Police said that Perry's bodyguard caught Chloe Ware early Thursday morning, but two others escaped. A phone listing for Ware could not be found. It was unclear whether she had an attorney.

Ware was charged with prowling and criminal trespass, then released. Police are still searching for two other suspects, Who and What.

* The man who sold his Southern California home to "Octomom" Nadya Suleman said Sunday that he's going ahead with eviction proceedings because she hasn't made a long-overdue $450,000 payment.

Amer Haddadin said that he'll evict Suleman if she and her lawyer, Jeff Czech, don't pay the balance on the house by Friday. A balloon payment was due Oct. 9.

"I think they have money, but they are hiding the money," Haddadin said.

It has to be in one of those darn kids.
