Actor, singer, producer and stand-up comedian Jamie Foxx has long been known as a quadruple threat, but now he has a fifth accolade to add to that list: party doctor.

The “Just Mercy” star single-handedly entertained everyone at Wednesday’s Avi & Co.’s cocktail bash, celebrating the luxury watch retailer’s collection of exclusive timepieces ahead of New York Fashion Week. Microphone in hand, the actor, 52, sang over the DJ’s tunes, told stories, joked with guests and posed for pictures.

Despite his upbeat mood, Foxx reflected with his friends on the loss of Kobe Bryant, who died in a tragic helicopter crash Jan. 26 along with his daughter, Gianna, and seven others.

“There’s no silver lining in it,” he tells The Post. “My kids were broken in half, like everybody was. If we can get anything out of it, it’s we need to move closer and get in proximity with people that you may not normally get along with or talk to. I see people change. I hope we can keep that energy up.”

Like Bryant, Foxx is a proud girl dad. “I call myself New Dad,” he says, explaining his parenting philosophy with daughters Corinne, a 25-year-old model and actress and Annalise Bishop, 11.

“You have to let them have their say, but you also have to bring Texas in and corral them. I want the discipline to be a certain level.”

Despite his wealth and fame, he takes care not to spoil his little darlings. “I don’t play the Hollywood stuff. They don’t get what they want if they don’t show some type of work ethic or some type of humbleness. You learn. If you give them too much on Christmas, they say, ‘We’re tired of opening presents.’ I say, ‘You won’t be tired next year because you’ll have one present!’”

He also wants to inspire his girls to aim high. “I took them to see Hillary [Clinton] when she was running, Oprah, all these women who are really making moves. I want them to see that.”

On the other hand, his daughters might not want to see their dad making moves on the dance floor. Foxx admits that his love of nightlife has embarrassed Corinne over the years — so much so that he claims the duo is developing a new TV show called, “Dad, Stop Embarrassing Me.”

He told the story of being out on the town when a car pulled up. “Oh my god, it’s Jamie Foxx! We go to school with your daughter!” squealed the girls inside. “Are you going to the club?”

Mortified Foxx mumbled, “No, you know what, as a matter of fact, there’s an open house up here …”

“I’m constantly embarrassing her, but you know what?” says Foxx. “She’s gracious enough and loving enough to forgive me.”
