The 27-year-old singer and actor has been romancing the ‘Booksmart’ director – who has son Otis, six and daughter Daisy, four, with her estranged husband Jason Sudeikis – for several months, and sources have now said the couple have “grown even closer” since rumours of their romance began swirling earlier this year.

An insider told ‘Entertainment Tonight’: "[They are] having an awesome time. [They have] been going on walks outside in the park and not hiding their relationship, [and have] grown even closer as a couple.

"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."

Harry and Olivia, 37, recently enjoyed down time in the UK together after working together on the upcoming movie, ‘Don’t Worry Darling’.

The pair were first reported to be dating in January after they were spotted holding hands while attending a wedding together.

A source previously said: "Filming during a pandemic in Los Angeles was pretty all-consuming. Now they're able to unwind, relax, and really enjoy some one-on-one time. Their idea of a good time is going for a long walk and ducking into a neighbourhood pub."

While a second insider added: "Harry and Olivia have been inseparable. Of course that’s in part because they’ve been in a bubble for their film, but even in the days since it wrapped, they’re still spending all their time together."

Meanwhile, it was previously claimed that chemistry between the pair was obvious when ‘Don’t Worry Darling’ began filming in September 2020.

The source said: "As they spent time together on-and off-set, their friendship quickly turned romantic. Their chemistry was very obvious. Everyone saw it coming. During breaks, he hasn't been able to stay away and visited her trailer.

"Olivia and Harry created this loving and warm environment. Everyone loved working with them. She takes her work very seriously, but everyone saw it coming."
