Actress Brooklyn Decker stars in the movie “What To Expect When You’re Expecting.” Model Brooklyn Decker has starred in the magazine Sports Illustrated. Wife Brooklyn Decker stars as Mrs. Andy Roddick and lives in Brooklyn. Lately that name Brooklyn’s dropped from more mouths than Marty Markowitz’s.

About this movie: “I play a Southern trophy wife who is very kept. And pregnant. I had to go for belly fittings. They put glue all over my stomach then stretched out the prosthesis for the appropriate time — six months, nine months. There are weights in it so you waddle correctly.

“A midwife was on the set daily to teach my appropriate waddling in 6- inch heels. One thing you learn is it takes longer to sit down.

“We filmed in Atlanta, where my husband grew up. Atlanta has great tax breaks. They’re doing 28 productions.”

Very interesting. More interesting’s how she got from cover girl to movie star.

“I’ve taken acting lessons for some time. I’m lucky. I’ve done three movies. But nobody sees my two years of failed auditions. Lots of rejection — and I’m still trying. When nobody knew my name or who I was, there were a few guest shots but dozens of TV shows and pilots I didn’t get. I’m used to the word ‘no.’ ”

OK. To the face. And that body.

“Trust me, the face is not the same as it was. I see the difference. I’m 25. Two years, and it’ll catch up to me. As to food, I eat what I like. Sweets. Candy. I enjoy that and can’t starve myself. I love camping, hiking. As a teenager, my mom started me lifting weights. She thought it’s a great idea to protect my bones.

“My skin I wash with Cetaphil. I have a glow, but it’s good makeup. I cover up spots. Jeez, I’m not all that great in person . . . And seeing myself all blown up on-screen? Times a million enlarged? My face looks like it’s been PhotoShopped. It’s unnerving.

“I’d never want my child to be a model. Before modeling I didn’t even have a passport, so in truth that’s helped me, but it’s a not fair industry. It’s hard work, which does not often equate to success.”

NEWLYWEDS Christine Quinn and partner Kim Catullo exchanged rings at their historic glorious ceremony, and the applause and cheers were thunderous. Andrew Cuomo, on wasn’t he nervous legalizing same-sex marriage: “I am never scared.” Mike Bloomberg, who brought his Diana Taylor a k a the first girlfriend, on Kim Catullo’s appellation should Christine Quinn become mayor: “I don’t know. Maybe first partner?”

NOT one to dodge a commitment, TV’s top-rated programee Judge Judy made it to Albany Sunday to honor a longtime commencement speech. That’s despite needing a cane and wheelchair. Saturday she spent at the office of foot specialist Dr. Rock Positano getting it examined, taped, bandaged and booted. Friday she wore a pair of new high heels and busted her ankle.

SNOOKI, no longer a rooky, is moving off “Jersey Shore.” Beer guzzling, craziness, party nutcases and 24/7 frat-house sex is no golden wholesome Mother’s Day image for an expectant mama. Exercising taste, even MTV sees the impropriety of mixing condoms with bassinets. Although wildly popular, she’s being phased out. Temporarily she’ll do both, but they plan to spin her into her own show. Translation: “Jersey Shore” will beach her.

BERNADETTE Castro, who once opened convertibles then became our state’s parks commissioner, is on to radio. She, Republican, is joining former Gov. David Paterson, Democrat, on WOR to see if the duo concept works.

LISA Marie Presley leaving Scientology? Maybe Kirstie Alley, too? That’s the rumor . . . A fan of JPMorgan’s Jamie the flawed Dimon: “His problem is ego.” . . . Ordinary Brit citizens renting boats, yachts, dinghies or floating bits of driftwood to share the same waterways at the same time as Queen Elizabeth’s Jubilee joyride.

LEVON Helm of The Band, just buried at Woodstock Cemetery, had financial problems. Medical bills and not much in the way of royalties. Most of The Band’s songs were registered under the name Robbie Robertson, The Band’s guitarist, from whom he’d been estranged since The Band unbanded in 1976. Robbie, unrequested by Levon, asked to visit the hospital and say goodbye.

My question: “Was Levon involved in writing those Band songs?” His friend, music p.r. Barbara Jacobs: “Yes. The lyrics are populated by characters from his life.” Robertson has stated publicly that Levon “didn’t write one note, one word, nothing.” About rumors rich Robbie paid the dead man’s debts, she said: “Nobody’s heard anything about that.”

SINGLE girl at a wedding: “To me a guy’s only macho if he has hair on his chest — and also on the hood of his Porsche.”

Only in New York, kids, only in New York.
