EXCLUSIVE: Photos provide evidence of Kristen Stewart’s infidelity behind her lover’s back! hue01

Kristen Stewart and Woody Harrelson reignited their friendship in a delicious new movie.

Speaking to Deadline at the Cannes Film Festival, the two costars opened up about bonding while shooting filmmaker Quentin Dupieux’s Full Phil — the story of a father and daughter on a food-filled trip to Paris — which premiered at the fest on Sunday, May 17.

“They had a very talented and willful French man making the food,” Stewart, 36, said of the shoot, which she added involved consuming plenty of rich cuisine onscreen without the advantage of a spit bucket.

“Our process means that I have to eat all day long,” the Oscar nominee recalled. “They wanted it to taste really good and reflect the French cuisine. And I was like, ‘I’m going to die. I’m not supposed to actually perish.’ ”

Stewart recalled she “only puked once” — when she could smell butter in a cauliflower mash dish, despite the chef insisting “it’s all vegetal oil.”

Harrelson, 64, who has reportedly stuck to a vegan diet for over 30 years, said he would “have had a spit bucket… I wouldn’t care.”

Writer-director Dupieux’s film centers on Harrelson and Stewart’s father-daughter duo touring Paris, with the former somehow symbiotically experiencing all his child’s eating and drinking. “She’s a voracious bottomless pit, eating her feelings,” Stewart told Deadline of her character.

“The eating’s cool because it’s nice to have obstacles,” she added, “like kind of hurdles that you don’t think about when you’re running lines… It’s very symbolic.”

Full Phil is the first time Stewart and Harrelson have collaborated after meeting back when she was around 17.

“She had just worked with Sean Penn and he was raving about her,” recalled the True Detective star. “And then I saw the movie [2007’s Into the Wild] and she was great in that. And then we hung out.”

“It was love at first sight,” the Twilight star said of first becoming a fan of the “f—ing cool” Harrelson in 1992’s White Men Can’t Jump. “He took me to a vegan spot in the valley and we totally bro-ed down… So when this popped up, I was like, ‘I’ve wanted to work with this guy forever.’ ”

Following its Cannes premiere, Full Phil does not yet have a release date.

Stewart next produces and stars in The Wrong Girls (in theaters Aug. 14), written and directed by her wife Dylan Meyer, plus miniseries The Challenger and the film Flesh of the Gods. Among Harrelson’s upcoming screen projects is comedy series Brothers costarring Matthew McConaughey.
