Nicole Kidman wants to stay 'healthy and vibrant' for her kids

London: Hollywood star Nicole Kidman says she works hard to stay fit and energetic so that she can take care of her kids. 

The 'Big Little Lies' actor, who has grown-up children Isabella and Connor with former spouse Tom Cruise and Sunday, nine, and Faith, seven, with husband Keith Urban, says her younger kids encourage her to make an effort with her appearance, reported Contactmusic.

"You have an almost 10-year-old and a seven-year-old - I mean, that's hard truth right there. They'll say, 'You're 50?' But it's interesting because particularly my little one will say, 'Please don't wear your work-out stuff to school this morning. Please blowdry your hair. Please wear some make-up. I did show up one morning looking like a wreck I suppose... And my daughter was mortified.

"I want to stay healthy and vibrant, I want to be able to take care of them... That's a big part of it when you have children when you're older,"
