Harry Styles' Relationship With Olivia Wilde's Kids: 'They Think He's A Superhero'

It will be two years since Harry Styles and Olivia Wilde made their romance public.

They've become so close that the "Watermelon Sugar" singer has already spent a lot of time with her children, Otis, eight, and Daisy, six.

Indeed, the "Booksmart" filmmaker had two very special VIP visitors for Harry's "Love on Tour" concert at the Kia Forum in Los Angeles on Tuesday.

The two kids went to the sold-out show.

In terms of Harry's relationship with the two youngsters, a source told Hollywood Life that the children regard the former One Direction member as their "very awesome big brother."

In fact, when kids see him perform on stage, they supposedly think he's a superhero.

Harry and Olivia were first seen holding hands in January 2021, shortly after her and long-term lover Jason Sudeikis revealed their engagement was off.

"Harry has become close to them; they're part of the package that Olivia comes with." He loves them because he loves her."

According to a second source, Harry Styles' "great bond" with the children means a lot to the actress-turned-director. They are, after all, her "everything."

"He has genuine conversations with them and remembers everything that is important; it is clear that he genuinely cares."

"And they're both completely captivated with him, it's extremely lovely," they continued. "Olivia is overjoyed that her children get along so well with Harry; it's only one of the many reasons she likes him."

Another significant positive for the British singer-actor is Olivia's ability to rely on him when things become rough.

In recent weeks, the former "House" actress has been embroiled in a contentious custody fight with her ex-fiance, which has taken a turn for the worse. Their former nanny also claimed in a tell-all interview with the Daily Mail last month that Olivia Wilde abandoned Jason Sudeikis for Harry Styles.

It then allegedly escalated into a full-fledged brawl in which the "Ted Lasso" actor threw a tantrum and lay on the ground in front of Olivia's car just to keep her from leaving their shared home.

However, Jason and Olivia denied the nanny's claims, claiming that the accusations leveled against them were "false."

They then accused the nanny of harassing not only them but also their friends and family.

"We will continue to focus on raising and protecting our children with the sincere hope that she will now choose to leave our family alone," the former couple's statement further said.
