ATRICK SWAYZE

, who's battling pancreatic cancer, has reportedly responded well enough to treatment that his doctors have given him permission to star this summer as an FBI agent in "The Beast," a new drama series from A&E.

"I can't wait to get to work on this," Swayze told the New York Times via e-mail.

"Obviously we've had candid conversations with him and his doctors, and we have a fairly high degree of expectation that Patrick will be good to work a full production schedule," A&E exec VP Bob DeBitto told the paper.

Swayze's diagnosis stalled A&E's announcement of the show, but the "Dirty Dancing" star was determined to do it.

"He was very passionate about the role," Sony studio executive Jamie Erlicht said. "He called us personally after he got the news and he told us: 'Guys, I have some horrible news. But if you can be patient and stand by me, I'm going to come back and do the show.' "

"He said: 'I'm in great condition. I'm a cowboy. I'm a dancer. I'll beat this,' " Sony executive Zack Van Amburg added.

From Britain with love

News of the World's Rav Singh reports that the break-up of Liv Tyler ("The Strangers") and Royston Langdon is off.

"Liv was reminded just how sacred marriage is," said an unidentified source. "She realized that for the sake of their three-year-old son, Milo, she wasn't prepared to turn her back on her vows."

* Also reunited are "Lost" looker Evangeline Lilly and former co-star Dominic Monaghan.

"They're as happy as ever now," an unidentified someone told Singh. "They love each other enough to give it a second go."

* The London Sun has the latest Lindsay Lohan sexcapade.

Although it would make filling this page much more difficult, we almost long for the day when men kissed and didn't tell.

The latest loser trying to latch on to Lindsay's fading celebrity is Bobby Brown's son "Brandon" (showbizspy.com says his name is Landon, which it actually seems to be - he's on the MTV reality show, "Rock the Cradle").

Brandon/Landon implies he did the deed - or at least did something resembling some deed - with Lindsay in a bathroom at a private party.

"Me and Lindsay got really, really close," Brandon/Landon said. "She followed me to the bathroom during a private party, and, well, we basically got together.

"I think she knew who I was when she first saw me."

Really? We still don't know who you are.

* Since the Sun couldn't get Brown's name right, we're not sure how much faith we can put into their item that 15-year-old Miley Cyrus is dating a 22-year-old backup dancer named Marshal.

Perez Hilton had the first photos of the couple canoodling.

Or not.

As for the next Miley . . .

"Extra" reports that 15-year-old Selena Gomez, the star of Disney Channel's "Wizards of Waverly Place," is going to abstain from sex until marriage.

"I said, 'Dad, I want a promise ring,' " Selena said. "He went to the church and got it blessed. He actually used me as an example for other kids. I'm going to keep my promise to myself, to my family and to God."

Nice PR move, kid.

A few decades ago, Brooke Shields made the "promise." Britney Spears also made it. Alas, no 15-year-old knows what they're doing this weekend, let alone as they mature into adulthood.

You want to save yourself until marriage, more power to you, but shut up about it - you're only going to look like a liar.

(Can any Tattle reader come up with one teen celebrity who made a public "Promise" and kept it?)

The only girls who can make a virginity pledge and hold to it are living in that polygynous compound in Texas - because they're getting married when they're 12.

* Anne Heche's five-year marriage to Coley Laffoon is officially over, and she must pay him $275,000 plus monthly child-support of $3,700 for the care of their 6-year-old son, Homer.

Heche will also pay 75 percent of Homer's private-school tuition.

It sure would have been cheaper to stay with Ellen.

* Vin Diesel better break out "The Pacifier." He and girlfriend Paloma Jimenez (shockingly, a model), have a baby girl, his rep said Friday.

Amazingly, People reported that the baby was born on April - that's April - 2. Diesel wasn't releasing the baby's name.

Hey, it took two months to release the baby's birth.

* The New York City Opera has commissioned Charles Wuorinen to compose an opera based on "Brokeback Mountain," which is scheduled to premiere in the spring of 2013.

As if gay men don't love opera enough already. *
