Jason Sudeikis is said to have gone into a tailspin after finding that his long-term partner Olivia Wilde had cheated on him with Harry Styles.

A former nanny who worked for Jason and Olivia stated in an interview that the actor was taken aback by her affair with the Grammy-winning singer.

Jason and Olivia apparently split up in early 2020 but declared they were separated 10 months after she and Harry started production on her directorial movie, "Don't Worry Darling."

Olivia apparently began spending more time away from home around this time, and the "Ted Lasso" actor discovered her alleged affair with Harry after he read the texts on her Apple Watch, which she had left behind.

Jason Sudeikis and Olivia Wilde reportedly had a massive quarrel on November 15, 2020, after the former observed her preparing a salad for the "Dunkirk" star in the kitchen. To prevent her from fleeing, he allegedly walked outside and put himself under her car.

"She walked back into the home and he went in, it was back and forth," the former nanny explained. He said he was doing it on purpose to make her late for Harry's appointment."

Following the event, Jason allegedly barred the nanny from playing the former boyband member's songs in their house.

She told the Daily Mail that she couldn't believe it when she spotted Olivia holding hands with Harry. This occurred during their January 2021 attendance at a friend's wedding.

"Just a month before when we were in L.A., she was sending Jason messages saying she loved him."

The nanny added that there were some days when the comedian was angry and cursed names at Olivia to her.

Jason would allegedly say, "I'm tired of this f--- s---. It's because of Olivia. She left us."

Olivia Wilde allegedly set off a chain reaction of unpredictable conduct in Jason, who became addicted to alcoholic beverages.

The nanny also stated that she left the family but was granted a six-month extension while they sought for a replacement.

Meanwhile, the nanny stated that Jason Sudeikis believes Olivia Wilde flirted with Harry Styles first, rather than the other way around.

She shared, "He started telling me details [of her relationship with Harry] and he said, 'She put the move on him. She put the first move on him.'"
