Nicole Kidman and Keith Urban are considered one of the strongest and most popular couples of Hollywood. The country crooner reveals the secret of their successful married life in an interview given to a publication.

Urban told Woman's Day in an interview that he nurtures their love like people take care of their garden. The singer said that he does the same things now, which he did while their courtship started.

The country crooner explained that it is like how one takes care of their garden. If the garden is not looked after properly, it tends to grow over. Then the owner starts complaining that the garden does not look good enough and starts looking for another garden.

However, he believes in maintaining his garden. The 52-year-old country music star revealed that his wife happens to be his best friend. He feels that there is no one else on this earth who knows him and the Bombshell actress.

Urban acknowledged that his marriage is a happy one because they love each other’s company. He said they are best friends and love to do all things together in another interview given in 2016. The country music star also said that they give each other the highest priority.

Meanwhile, the 53-year-old Aussie actress said a few years ago that they were happy because of their urge to help and protect each other. They also have a strong sense of gratitude towards one another.

The Oscar Award-winning actress told a publication in 2017 that she and her husband are extremely lucky to have each other in their lives. A year later, the Eyes Wide Shut actress told another publication that their strong verbal communication is the secret to their successful marriage.

Nicole Kidman revealed that they never texted one another as that could be misleading each other. Rather, she and Keith Urban FaceTime and keep chatting all the time. The gorgeous mom-of-four mentioned that she and Urban always like to call each other.

It was in 2006 when the couple got married at the suburb of Manly in Sydney, Australia. They exchanged their vows just a year after meeting each other in Los Angeles at the G’Day USA Gala. The couple shares two children – their daughters Sunday and Faith.

Nicole Kidman was married to Hollywood heartthrob Tom Cruise for more than a decade before her relationship with Keith Urban, Daily Mail reports. The former couple had adopted two children while they were married.
