Nicole Kidman felt lonely after her divorce from Tom Cruise

She recalled thinking: "I still don't have a life, what is wrong with me? Who do I jump on the bed with, and order pancakes with?"

However, the 'Big Little Lies' actress - who has kids Isabella, 24, and Connor, 22, with Tom - has found a person to share life's experiences with in husband Keith Urban.

The 'Lion' star - who has daughters Sunday, nine, and Faith, six, with the 49-year-old country musician - couldn't be happier and as she reaches the milestone age, she admits she still pretends she is 21.

Asked about turning half a century, she told The Daily Telegraph newspaper: "It feels sort of like an accomplishment. But I still try to conduct myself with the abandon of a 21 year old."

The blonde beauty will spend her birthday surrounded by her family.

She said: "My sister is coming over with her children and it will just be family. I am so happy with that."

Nicole - who has her own production company Blossom Films - has achieved a tremendous amount during her career, but she is yet to direct a movie, something she hasn't ruled out.

Asked if she sees herself helming a movie, she replied: "Who knows? Hopefully it ain't over yet."

Despite turning 50 this year, the actress previously said she is getting more work than ever.

She said: "I'm turning 50 this year and I've never had more work than right now. And that's partly because I work in television, I can work on films that are made to be shown on a small screen and I can work on films shown on a big screen. As an actor I get to work in all of the mediums."
