Nicole looked typically stylish in a blush-coloured smock with frill details and long sleeves, paired with a brown leather tote bag and tan ballet flats.

The Undoing actress wore minimal makeup, allowing her age-defying complexion to shine through.

She also threw her strawberry blonde tresses up into a no-fuss chignon. 

Meanwhile, country crooner Keith showcased a glimpse of his tattooed chest in an polka-dot shirt, matched with a pair of skinny black jeans and suede boots.

The beloved showbiz couple smiled briefly at onlookers as they departed the restaurant, before jumping into a parked limousine and driving away. 

It comes after Keith revealed the secret behind his long-lasting marriage to Nicole, telling Woman’s Day magazine that he he ‘tends’ to his love like a garden.

‘I do the same things I did at the beginning when we started dating,’ he said in October.

Speaking metaphorically, he explained: ‘It’s tending to the garden. If you don’t do the work, the garden starts to grow over, and then you complain that the garden is not very interesting and you look for another garden. I maintain this garden.’

The musician added: ‘Nicole is also my best friend. I’ve never had anyone on the planet who knows me as well as she does.’  

Nicole said in February 2017 that she and Keith had defied the odds because of their mutual sense of gratitude and ‘desire to protect and help each other’.

‘Keith and I always say that we are just so lucky to have each other,’ the Oscar winner told News.com.au. 

‘In this world, to be able to come back to that love and that strength is so nourishing and powerful.’

A year later, in June 2018, the Big Little Lies star told Parade magazine that the secret to their marriage was verbal communication.

She said: ‘We’ve never texted. We talk all the time and we FaceTime, but we just don’t text because I feel like texting can be misrepresentative at times.

‘I’ve had the thing where I re-read texts and I’m like, “What does that mean?” and then read it to somebody and go, “Can you interpret that?”… I don’t want that between my lover and I.’ 

The couple share two daughters: Faith Margaret, 10, and Sunday Rose, 12.
