When it comes to dating, they have to be cunning.

The three daughters of Sylvester Stallone, Sophia, Sistine, and Scarlet, have learnt to discern men’s actual intentions based on whether or not they mention their well-known father during their first date.

“The giveaway is if they mention it on the first date, we’re like, ‘Okay, you’re here for the wrong reasons,’” Sistine, 25, told The Post ahead of the Season 2 premiere of “The Family Stallone,” on Feb. 21.

“If they’re casual then, okay, it’s not going to be an issue. But 90% of the time that’s what we get.”

One of the prospective suitors for Sistine, the middle sister, brought a pair of boxing gloves and asked if she and her father could sign them. Sistine’s first dates were filmed for the Paramount+ reality series.

“I’ll own it, not proud of it, but I’ll own it,” she said.

The eldest, Sophia, 27, said “There is a pressure when you’re the oldest” to settle down and “hit that timeline.”

“I’m starting to realize that it’s so not important anymore. They’re on their own path as much as I am,” she said.

“I know when my timing is right. And I definitely would say if I got married five years ago, it would be a disaster and I’d be divorced at 30.”

The only Stallone sister currently in a relationship is the youngest, Scarlet, 21, who is dating Louis Masquelier-Page, 21, a British native she met at college, who is featured in the series.

“I wouldn’t even let him come on the show if I didn’t know how much he meant to me because my relationship is so private and I care about it so deeply,” she gushed. “I see us lasting for a very long time.”

The trio, who grew up in Los Angeles, said the motto their father ingrained in them, “DTA,” which stands for “Don’t trust anyone,” has also helped them test romantic relationships.

“He always kind of put it with protection and protecting your heart … never give yourself fully until you can truly let someone in when they’ve shown proof that they will treasure it,” said Sophia.

Scarlet said their dad even gifted them “jewelry that says DTA on it with a snake wrapped around the T.”

“He gave it to us when we were 14,” she said.

However, the girls’ mother, Stallone’s third wife, former model Jennifer Flavin, taught them to be less guarded.

“We trust everyone and that’s because of mom,” said Scarlet. “She’s sweet to everyone.”

The sisters also said they apply their dad’s belief in astrology to dating.

“His mom was a rumpologist [reading the lines, crevices, dimples, and folds of the buttocks] so my dad was taught a lot about astrology growing up and he instilled it in us with, like, crystals and zodiacs,” said Sophia. “[But] we don’t say to a guy, ‘We’re not going out with you.’”

“That’s such a lie, we definitely do,” interrupted Sistine. “If he’s a Scorpio, ‘Oh, we gotta go.’”

Sophia waits until the third date to ask a guy about his astrological sign.

“They have to like me first before I can show that crazy side,” she said.

Whether or not the sisters meet Sly and Flavin depends on how they introduce the men they’re dating to one another first.
