Ticket sales to “Slave Play” skyrocketed following Kanye West and Julia Fox’s date night to see the Broadway show, according to playwright Jeremy O. Harris.

“Julia writing [in Interview mag] about going to see the play did amazing things for our audiences… We basically quadrupled our ticket sales that week because of the ‘Julia-Ye effect,’” Harris told Page Six at the opening of Cecily Strong’s new one-woman show “The Search for Signs of Intelligent Life in the Universe” at the Shed on Tuesday.

“I am very grateful to them because it means my little play can keep going even in this really fraught time,” he continued, adding he thinks the new couple is “fab.”

“I love people meeting people and having a good time.”

Gucci-clad Harris was already friends with Fox — a fixture on the downtown scene — and told us how the couple wound up seeing “Slave Play,” after they’d watched Harris’ recent film. “Zola.”

“They watched ‘Zola’ together,” Harris, who co-wrote the movie, explained. “The next day [West] reached out to me and the director [Janicza Bravo] with very kind words and said, ‘What else of yours can I see?’ and then immediately came to see the play the next day and was so kind.”

“Zola” was based off a viral Twitter thread about two strippers’ misadventures on a wild road trip to Florida.

West and Fox met on New Year’s Eve in Miami, and had dinner at Carbone before jetting to NYC as part of their whirlwind romance. After they saw “Slave Play,” they headed to dinner with Harris at Carbone, all with West’s personal photographer in tow.

West and Fox were most recently spotted at dinner at Craig’s in LA with former Tampa Bay Buccaneer Antonio Brown.

“Slave Play,” about a radical therapy for interracial couples that involves role play, was nominated for 12 Tony Awards, but did not win. It opened to rave reviews in 2019 and ran through through January 2020, before it officially reopened again Dec. 2.

Harris is a co-producer on Season 2 of “Euphoria,” and appears in this season’s “Emily in Paris.” He also appeared in the “Gossip Girl” reboot, and wrote a play for an episode of the show that’s being commissioned by the Public Theater. He is also developing a pilot for HBO.
