Jason Sudeikis films Ted Lasso as seen for the first time since Olivia Wilde dating Harry Styles

Jason Sudeikis kept things casual as he got to work on the set of hit series Ted Lasso in London on Friday.

The actor, 45, sported a brown flat cap and laid-back blue jeans as he arrived for the day’s shoot and later gave some direction to co-star Hannah Waddingham.

It comes just weeks after Jason’s ex-fiancée Olivia Wilde, who he shares two children with, was romantically linked to Harry Styles following their split.

Olivia and Harry were first romantically linked in January after they were seen holding hands at his agent’s wedding in Montecito, California. 

The new couple previously worked together on Don’t Worry Darling, which began filming in Los Angeles and Palm Springs back in October.

Wilde directed and appeared in the 1950s-set psychological horror, which stars Styles, Florence Pugh, Gemma Chan, KiKi Layne and Chris Pine.

A source told DailyMail.com that the couple stayed together at James Corden’s house near Palm Springs during filming, where they were able to ‘be alone and keep their relationship very secret.’

Another source said that the nine-year relationship between Wilde and ex-fiancé Jason Sudeikis, 45, officially ended in early November 2020, and they were together ‘as recently as this fall.’

According to People, Sudeikis wasn’t even aware that Wilde wanted out of their engagement until October, around the time her relationship with the One Direction alum took off.   

The insider added: ‘Jason feels that the timeline that Olivia and Harry would like people to believe – that she and Jason split ages ago, long before she became involved with Harry – is simply not accurate. 

‘She began filming [Don’t Worry Darling] in September, and by October, he began to get the impression that she wanted out. By November, they’d announced their split.’

The source emphasized ‘that’s how quickly it happened,’ adding that ‘none of it happened until she began filming with Harry.’ 

However, another person close to the couple disputed that interpretation: ‘Olivia and Jason were broken up as of early 2020. 

‘The recent news that she has moved on is no surprise. Olivia and Jason’s relationship continues to be focused on their children and co-parenting them.’ 

And another source told People that Sudeikis ‘is absolutely heartbroken about the split’ and her budding onset romance with Styles, as he hopes to ‘repair things’ in their relationship. 

The insider said: ‘There is still a lot of love there, and he would like to have hope that maybe there’s a way for them to repair things. But what happens next remains to be seen.’  

It was originally reported that Wilde and Sudeikis underwent an amicable split earlier in 2020, and they’ve since been adjusting to co-parenting their two children.

They began dating in November of 2011, later getting engaged in January of 2013, and they share son Otis, six, and daughter Daisy, four.

The exes met at the after party for the season 36 finale of Saturday Night Live, striking up a romance a few months later.

Sudeikis recounted the story on The Late Show in 2017: ‘I actually came off looking a little cooler than I really am because I had heard through the grapevine, through mutual friends who weren’t exactly her best girlfriends, who would report back, “Oh you know, I think she’s dating someone.” 

‘So I didn’t make any moves. I was just very, very busy with other things. And next thing you know, I stopped being busy, she stopped dating someone, and then it was off to the races. We sort of reintroduced ourselves. The universe had more in store for us in the fall.’ 

Both had just gotten out of previous marriages, as Wilde was married to Italian Prince Tao Ruspoli, 45, from 2003 until filing for divorce in March of 2011, two months before meeting Sudeikis.

He married Pitch Perfect writer Kay Cannon, 46, in June of 2004, before separating in 2008 and divorcing in 2010.

The former couple starred together in the 2013 romantic drama Drinking Buddies, and he later appeared in her 2019 feature directorial debut Booksmart. 

Wilde told People of directing her ex-fiancé: ‘That was great. He’s one of the best improvisers in the world so I knew I could cast him. He’s like spinning a top and just letting it roll. It’s really amazing to see him do his thing.’
