‘Valenswine’s Day’: When pigs romance mistresses

If Feb. 14 is for drugstore chocolates and bodega flowers, then today is for blue Tiffany boxes and lingerie.

That’s because Feb. 13 is “Valenswine’s Day,” when cheating husbands take their mistresses out on the town — and luxurious restaurants and hotel bars see busy corner tables and telltale age gaps.

“There’s a lot of hand-holding and eye-gaz ing,” said Scott Stamford, general manager of romantic River Cafe in DUMBO. “We have to be discreet. Sometimes it’s even people we know.”

Some cheaters will be so brazen as to make two reservations at one restaurant a day apart — and tip off the maitre d’ that he shouldn’t remark on the revolving door of women.

“They don’t want us to tell him, ‘Oh, hi again,’ ” said Rosanne Mar tino, a general manager of the West Village restaurant One if by Land, Two if by Sea.

And “Mistress Day,” as it’s known, has increasingly become a misnomer as more cougars have gotten in on the action.

Tony DeLorenzo, a private in vestigator for All State Investi gations, caught a 40-year-old woman shacking up with her young, buff gym trainer last Feb. 13.

“Valentine’s Day is like our Christmas,” DeLorenzo said, noting that he chases a dozen cheaters on a typical Mistress Day. “It’s so rampant in the city.”

Sadly, the wives typically get shorted in this erotic equation.

While the missus receives candy and flowers, the mistress is lavished with en graved Cartier jewelry, fine wines and limos at her door step.

Last Feb. 13, one married 59-year-old financial planner paid for his 30-year-old mistress to spend the day at the spa, get her hair coifed and pick out a new dress from Barneys, recalled the lucky lady, who declined to give her name.

A chauffeur delivered the petite brunette to the corporate honcho’s uptown loft, where a private chef whipped up tiramisu and uncorked a bottle of brunello di Montalcino.

As for the wife, he had simply told her that business called for the weekend.

“He kept his cellphone on silent in his desk drawer. Not on vibrate, on silent,” recalled the brunette, who is accompanying another married man this Mistress Day.

DeLorenzo remembers catching one well-heeled cheater at a Manhattan restaurant after he parked a brand-new black BMW in front for his girlfriend.

With the soft economy, the wife’s share of the gifts has only shrunk, he said. The mistress also tends to get more public lovey-dovey affection.

Another telltale sign of a tryst? Couples dashing out of cabs and up to their hotel rooms.

“They don’t hang out in the lobby,” said Douglass Miller, a former manager at the Four Seasons and instructor at the Culinary Institute of America.

But all the juicy juggling can get confusing.

“Jordan,” a student who was out with a married, 39-year-old physician on a recent Feb. 13, got a Valentine’s Day card from him while dining at the posh Upper East Side restaurant Daniel. Tucked inside was a grand in cash — and a handwritten message to his wife.

She pocketed the card and left him with some advice.

“I told him to have a nice Valentine’s Day with his wife,” said Jordan, 32. “He didn’t find that as amusing as I did.”

Fed-up wives have also exacted sweet revenge during the holiday.

Instead of showing up for a lavish meal with her cheating husband at One if by Land, Two if by Sea, one woman sent court papers.

“I imagine that was the worst-tasting meal they’ve ever served,” said Paul Edelstein, her attorney. hhaddon@nypost.com
