Meanwhile, Olivia hasn't missed her Don’t Worry Darling co-stars concerts this year, coming out to his shows to support her man.

The O.C. alum also had her close friends were in the arena at his October 4 concert, per US Weekly.

Her signs of love and appreciation toward the "Watermelon Sugar" singer also extended to her choice of outfit for the Gucci “Love Parade” fashion show earlier this month, when Olivia appeared to sport Harry's cross pendant, Page Six is reporting.

Although Olivia and the father of her children have both moved on romantically with other people, the former couple reportedly maintains a close bond and is dedicated to co-parenting Otis and Daisy as harmoniously as possible.

In a 2018 interview with US Weekly, Jason shared the secret to being a good parent was “staying around.”

“Being present is a good quality,” said the SNL star. “At least I’ll know how I screwed them up!”

Likewise, Olivia dished on how she balances work and family time by focusing on things “day by day, step by step.”

“I think it’s just biting off as much as you can chew, you know, slowly and incrementally,” she told the outlet in 2019. “And I think [it’s] knowing what you’re getting yourself into.”
