WATCH | Olivia Wilde’s kids spotted dancing with Harry Styles' mom at his concert in an adorable video

Who needs backup dancers when you have Olivia Wilde’s delightful kids?

The 37-year-old actress took her kids, seven-year-old Otis and five-year-old Daisy, to her beau, Harry Style’s Love on Tour concert in San Diego.

Although the Watermelon Sugar singer was the main attraction, Olivia’s kids and Harry’s mom, Anne Twist, stole the limelight.

In a video shared online, which has over 121 000 views, Anne and Otis can be seen dancing the night away to the One Direction hit What Makes You Beautiful.

In another video, the Booksmart actress, who has attended several of Harry’s shows, can be seen dancing and jumping around with her kids as the Adore You singer belted out his hits.

A source close to Anne revealed that she has given Olivia her stamp of approval.

“Anne says Olivia and Harry are the perfect match because she keeps him grounded,” the source told Life & Style.

“She can’t wait for Harry and Olivia to have a baby, she keeps saying, ‘I hope it happens soon!’ No one would be shocked if it does because Harry definitely has baby fever.”

Harry and Olivia confirmed their relationship in January after they were snapped holding hands at his agent's wedding at the San Ysidro Ranch in California. A source said at the time that they’d been together for a while.

“They were in Montecito, California this weekend for a wedding,” said the insider. “They were affectionate around their friends, held hands and looked very happy. They have dated for a few weeks.”

Another source revealed that the pair first met on the set of the movie, Don't Worry, Darling, after Olivia, who directed the film, cast the British singer in the movie.

“Olivia and Harry are together for long days on set and have gotten to know each other really well, so it's all very organic.

“[Olivia] wouldn't let a romantic relationship get in the way of a professional one, so anything they're doing is being done thoughtfully,” the source said.

The pair have been spending loads of time together, often enjoying “walks outside in the park”.

Another insider said: “Yesterday, they enjoyed lunch outside and looked incredibly cute together.

“They were both in a great mood and left the restaurant holding hands. Harry put his arm around Olivia as they walked back to her house.”

In July, the American actress and the Falling singer were seen kissing, hugging, and swimming in Tuscany, while wearing matching blue swimsuits.  

“Harry has been seen taking a break on the beach in Porto Ercole after he finished filming My Policeman in London,” a source told Page Six.

The doting couple have been tight-lipped about their relationship, which Harry says has helped him maintain a balance between work and his personal life.

“I've always tried to compartmentalise my personal life and my working life,” he said in an interview with Dazed.

Confirming Harry’s sentiments, a source close to the couple revealed that Harry and Olivia have a deep respect for each other's crafts.

“Olivia and Harry have an ease to their relationship, they love and support each other, but also let each other be free and work on their own,” said the insider.

“Both of them respect the other’s work and never want to get in the way of each other.”
