Woody Harrelson partied all night with his wife Laura Louie and two of their daughters while celebrating the premiere of his new movie, “Champions,” in New York City Monday night.

At the premiere, Harrelson, 61, and Louie, 55, walked the red carpet with their kids Deni, 30, and Makani, 16. Their other daughter, 26-year-old Zoe, did not attend the event.

A spy told Page Six on Tuesday that after the family members posed for photos on the red carpet, they all sat together inside the theater to watch the film.

However, the real celebration happened at the film’s afterparty. Harrelson and his brood got in a private car and made their way to the Ascent Lounge at the Time Warner Center where we’re told they partied until around midnight.

“They celebrated his film in a private elevated table off to the side,” the spy said, adding that Harrelson “seemed to be enjoying himself” and even changed out of his red carpet look and into a gray and white pinstriped button-down for the late-night festivities.

The source noted, “Harrelson stopped several times to take photos with different cast members from the film.”

In the movie, Harrelson plays a former minor league basketball coach who receives a court order to manage a team of players with intellectual disabilities. “Champion” will hit theaters on March 10.

Harrelson seems to be on a partying hot streak. Page Six reported that the actor partied until 4 a.m. after hosting “Saturday Night Live” this weekend at L’Avenue at Saks.

A source told us that Harrelson, who was there with his wife and one of his daughters, was chatting with “Weekend Update” host Colin Jost and wife Scarlett Johansson at the party.

Other guests included Emma Stone, Justin Theroux and John McEnroe, as well as “SNL” boss Lorne Michaels and cast members Michael Che, Bowen Yang, Heidi Gardner, Sarah Sherman, Ego Nwodim, Marcello Hernandez, James Austin Johnson, Molly Kearney, Michael Longfellow and Devon Walker.

Despite the good energy around him that evening, the “True Detective” star had been dragged by critics after he shared COVID-19 conspiracy theories during his “SNL” monologue.

A source told us no one brought up the strange monologue during the swanky fête.
