Julianne Moore: Kids drive me crazy

Julianne Moore's children are driving her "nuts".

The actress has a son Caleb, 15, and a daughter Liv, who has just turned 11.

She misses the days when her kids were tiny and easily amused.

“My son is six feet tall and still growing. It’s really crazy," Julianne shared with the Chicago Sun-Times. "My daughter Liv is in middle school. The drama of that age can drive you nuts.”

The 52-year-old red-haired star plays a mother in her new movie What Maisie Knew.

In the drama, Julianne's character is a rocker who neglects her young daughter while engaging in a bitter custody battle to spite her ex-husband.

Julianne says her experience of being a mom helped her with the part, but also posed problems when arguing with her cheeky teen daughter.

"My daughter made a joke while we were in production. One day she said to me, ‘Mom, are you still playing that horrible mother?’" Julianne laughed. "The great part about it is we shot the movie next door to my house. So my own daughter came and hung out. Hopefully because I am a parent, I know the rules of good parenting. What’s so dangerous about this woman I play in Maisie is that she’s inconsistent, which really disturbed me. This woman would smother her daughter with love, affection, toys and clothes and then would be emotionally absent or yell at the poor little girl."

Julianne shared her life advice based on her three decades in the movie industry. She puts her career success down to sheer determination and effort.

"All I can say is try to do something in life that makes you happy. I’d also tell them that age brings clarity and hard work still pays off. Basically, you don’t know that at age 18," she finished. "You walk around thinking some people just get lucky and their lives fall into place. I’m here to say that persistence and hard work is the key to everything."
