Keith Urban is reportedly pleased his wife Nicole Kidman‘s latest age-gap rom-com didn’t appeal to critics.

The 57-year-old Hollywood star’s new Netflix movie, A Family Affair, starring Zac Efron, 36, received a poor critical reception and the country musician is ‘secretly thrilled’ about it, according to New Idea magazine.

Efron takes on the role of vain movie star Chris Cole, while Kidman portrays writer Brook Harwood, who is the mother of his long-suffering assistant Zara (Joey King).

An insider told the magazine it didn’t sit right with Keith, 56, seeing his wife get cosy with Zac, after the pair last portrayed lovers 12 years ago in the buzzy crime drama The Paperboy.

‘He absolutely trusts Nicole but it unnerved him seeing her get so cosy with Zac on-screen a second time around,’ the source said.

‘She likely won’t be doing a third, which, deep down, has made Keith happy to no end — something he’s having to keep to himself of course!’

Kidman and Efron do their best to heat things up in Netflix’s hotly anticipated May-December rom-com A Family Affair – but the result is a rather tepid affair.

Their characters fumble together in a tipsy hook-up – but after a sizzling start, their on-screen chemistry quickly goes cold.

It comes after Nicole revealed her daughters Sunday Rose, 15, and Faith Margaret, 13, give her honest feedback when she asks them.

Speaking with People, she said her girls are ‘very supportive’, however they also tell her their unfiltered criticism.

‘But they’re also like, “Ok, calm down,” the Australian actress, who shares the two daughters with husband Keith, said.

‘But I do think it’s important not to have sycophants [around you].’

Nicole and Keith also just celebrated their 18th wedding anniversary on June 25.

The Practical Magic star said it’s not about ‘seeking out really horrible criticism.’

‘We’re all a work in progress as they say,’ she added.

She has two children with ex husband Tom Cruise: Isabella Jane Cruise, 31, and Connor Antony Cruise, 29.

Nicole and Keith celebrated their 18th wedding anniversary on June 25.

Nicole commemorated the special moment with a sweet snap of her and Keith by the ocean.

Keith played the guitar while Nicole lounged next to him; she added the caption: ‘Forever,’ adding a heart and hashtagged Happy Anniversary.

The lovebirds first met on January 15, 2005 at a G’Day USA gala in LA; Nicole and Keith are both from Australia.

They had exchanged numbers but he did not call her for four months – with the couple going from strength to strength soon after reuniting over the summer.

They announced their engaged in May 2006 and one month later – on June 25, 2006 – married in Sydney.

They welcomed daughter Sunday in 2008 and daughter Faith in 2010.
