In October, Keith, 53, revealed the secret to his 15-year marriage to Nicole, telling Woman’s Day he ‘tends’ to their love like a garden.

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

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

While Keith admits that his relationship – like maintaining a garden – takes work, he has also said that marriage is easy because he and Nicole ‘just love being together’.

‘We’re best friends and we love doing everything together – we’re the priority,’ he told 2Day FM in September 2016. ‘Everything else comes after that.’

The couple married in the Sydney suburb of Manly in 2006, a year after meeting at the G’Day USA Gala in Los Angeles. They share two daughters, Sunday and Faith.

Prior to her relationship with Keith, Nicole was married to Tom Cruise for 11 years.
