The cast of “The White Lotus” Season 4 have been living their best lives while shooting on the French Riviera.

Kumail Nanjiani exclusively told Page Six that because they’re been shooting so long on location, all the cast does is hang out, so the bonding has been “incredible.”

“Often, we’re all living in the same hotel, so it’s kind of like being in a college dorm,” he explained.

The upcoming season of the HBO show is set in France, filming at the Airelles Château de la Messardière in St. Tropez and and the Hôtel Martinez in Cannes, according to Warner Bros Discovery. 

“You walk out of your room and everybody there is someone you know,” Nanjiani — who is currently promoting his partnership with Purina’s cat litter brand, Tidy Cats —  told us.

He added, “The cast has gotten very, very, close. We have breakfast together, lunch together, dinner together.”

Created by Mike White, each season of the hit anthology series follows a different cast of entitled guests and beleaguered staff at a branch of the fictional resort.

The cast typically stays in the hotels where the show films, which previously included Hawaii, Sicily and Thailand.

HBO hasn’t announced a premiere date for Season 4 yet, but confirmed that it will be set during the Cannes Film Festival. 

In addition to Nanjiani, the cast includes Laura Dern, Chris Messina, Charlie Hall, Steve Coogan, Max Greenfield, and Rosie Perez. 

“I’ve never worked with a cast this size, [where] I’ve gotten this close to every single person,” Nanjiani said. “All the little groups are fun. The one-on-ones are fun. The big groups go out together, sometimes. That’s fun.” 

He gushed over White as “an incredible director” and said, “It’s really been one of the best professional experiences I’ve ever had.”

Each season of “The White Lotus” is centered around the death of a hotel guest who doesn’t get revealed until the finale.

The “Silicon Valley” star noted that real hotel guests have come up to him and tried to get him to reveal things about the latest season.

“I’m like, ‘I can’t tell you, but I do know.’ I know everything. I know what the big mystery is, but I can’t tell anyone,” he said.

Nanjiani, who co-wrote his Oscar nominated 2017 movie “The Big Sick” with wife Emily V. Gordon, told us, “I haven’t even told my wife!”

He also recalled the day the news was announced he was cast in the new season, saying he was completely overwhelmed by the response from friends and family.

“I got like hundreds of texts. I’ve never had this many texts over the announcement of a job. It was non-stop…completely flooded,” he said.

As for his latest partnership with Purina, Nanjiani — who recently adopted a kitten named Biscuit after the devastating loss of his 17-year-old cat Bagel — often talks about his love of cats in his stand-up routines.

The new YouTube spots for the brand spoofs “Law & Order: SVU” with a “Special Litters Unit.” 

“I thought it was really funny –  I really do think cleaning a litter box is really important,” he said.

He explained that there’s also a “kitty litter cleaning scene” in “Sex Criminals,” his other upcoming show with Gordon that “nobody wanted in there.”

“But Emily and I were like, ‘No, it’s gotta be in there!’ and I think it’s great.”
