WHEN UNDERGOING a double mastectomy, a good surgeon and tons of support are essential.

The spouse or partner has to be fully on-board for a complete recovery.

Following news that Angelina Jolie had the operation after she learned she carried the breast-cancer gene (and her mother died of cancer), her longtime partner, Brad Pitt, spoke.

"Having witnessed this decision firsthand, I find Angie's choice, as well as so many others like her, absolutely heroic," he told the Weekly Standard in a statement, which also thanked their medical team.

"All I want is for her to have a long and healthy life, with myself and our children," he said. "This is a happy day for our family."

There's a glass half-full guy for you.

Angelina, who could easily have hidden her surgery with the best prosthetics and fashions money could buy, chose to tell all in an op-ed in yesterday's New York Times.

"I choose not to keep my story private," she wrote, "because there are many women who do not know that they might be living under the shadow of cancer. It is my hope that they, too, will be able to get gene tested, and that if they have a high risk they, too, will know that they have strong options.

"I am fortunate to have a partner, Brad Pitt, who is so loving and supportive," she continued. "So to anyone who has a wife or girlfriend going through this, know that you are a very important part of the transition. Brad was at the Pink Lotus Breast Center, where I was treated, for every minute of the surgeries. We managed to find moments to laugh together. We knew this was the right thing to do for our family and that it would bring us closer. And it has."

So learn your family's cancer history, ladies, and talk to your doctor.

Belated Happy Mother's Day.

Free Jaden Smith?

Jaden Smith, son of Will and Jada Pinkett Smith, reportedly wants to be emancipated when he turns 15 this year.

And Will and Jada seem willing to do it.

The pride of Overbrook told the London Sun, "[Jaden] says, 'Dad, I want to be emancipated.' I know if we do this, he can be an emancipated minor, because he really wants to have his own place, like ooh."

Listen up, Jaden. Having your own place isn't all it's cracked up to be - especially when your parents live in a palace.

You want to start dealing with plumbers? Exterminators? Cable installation?

Seriously, is living the good life with mom and dad so difficult? Are they too strict?

Uh, no.

"We generally don't believe in punishment," Will said. "From the time Jaden was 5 or 6 we would sit him down, and all he has to do is be able to explain why what he did was the right thing for his life."

Whoa. If Jaden's room is going to be empty . . .

The New York Daily News reports that in order for Jaden to get emancipated, he would need to file court documents (doable), get married (we don't think Kylie Jenner is ready) or join the military (you can be darn sure that's not happening).

What is happening? Clever promotion for the upcoming Will-Jaden-M. Night Shyamalan sci-fi film, "After Earth."

Beyonce canceled her show last night in Antwerp, Belgium, because she was a) dehydrated, b) exhausted, c) pregnant, d) phlegmish.

The answer is anything but c).

* A jury yesterday awarded Hong Kong businessman Richard Suen a $70 million judgment against billionaire Sheldon Adelson's Las Vegas Sands Corp.

Suen claimed that he was owed up to $328 million for helping the Las Vegas-based company secure a gambling license in Macau, the only place in China where casino gambling is legal.

Las Vegas Sands attorneys argued that Suen was owed nothing because he didn't make good on a promise to aid company executives. The case was a retrial; a jury's 2008 finding for Suen was thrown out on appeal.

The retrial jury deliberated for less than two days before reaching a unanimous consensus, but the nine-year suit is likely to continue. Sands spokesman Ron Reese said the company will roll the dice once again and appeal.

* When we spoke to Billy Crystal for his Christmas movie, "Parental Guidance," he said that the most satisfying thing he ever did was his autobiographical play, "700 Sundays."

Prepare to be satisfied again, Billy. "700 Sundays" will return to Broadway for a nine-week run beginning at the Imperial Theatre in November.

Bill Hader told the New York Times that this Saturday's season finale of "Saturday Night Live" will be his final show.

Until he comes back next season to guest host.

"It was a hard decision, but it has to happen at some point," Hader said. "It got to a point where I said, 'Maybe it's just time to go.' "

With head writer Seth Meyers leaving and Jason Sudeikis always on the verge of leaving, "SNL" could face a huge turnaround this summer, with a major need for a new "Weekend Update" anchor.

Might we humbly suggest the underutilized Nasim Pedrad.
