Olivia, who at 36 is ten years older than Harry, has previously spoken of her delight at landing the pop star for the part which she is also directing – gushing about his “confidence” and willingness to experiment with his gender and appearance.

But pals have revealed their friendship quickly grew into romance after shooting began in the US last year – and this weekend they are understood to have attended a pal’s wedding hand-in-hand.

A source said: “They clicked immediately – they’re both very artistic, passionate people and it was one of those things where straight away everyone could see they had a spark.

“It’s no surprise something has happened, but now they’re quite open about it and out and about as a couple. They went to a wedding together with a lot of their friends there.

“Clearly they’re enjoying themselves and the age gap really isn’t a thing. Harry has obviously famously had a thing for older women but he’s just extremely mature himself, you’d never think there was a decade between them.”

Olivia was previously married to an Italian aristocrat, Tao Ruspoli, after tying the knot in 2003, but the paid separated in March 2011.

Later that year she began dating fellow actor Jason Sudeikis, 45, becoming engaged in 2013 and going on to have two children together. But two months ago they announced they had separated at the beginning of last year.

Harry, who splits his time between New York and north London, and has previously enjoyed high profile romances with Kendall Jenner and Taylor Swift.

His most recent relationship with model Camille Rowe inspired his latest hit album, Fine Line, but the couple separated in 2018.

A string of daring fashion choices including wearing dresses in photoshoots for Vogue magazine has prompted question marks over his sexuality – but Harry has insisted he does not want to label it and explained: “I want things to look a certain way.

“Not because it makes me look gay, or it makes me look straight, or it makes me look bisexual, but because I think it looks cool. And more than that, I dunno, I just think sexuality’s something that’s fun.
