Nicole Kidman has expressed the hope that former husband Tom Cruise and his new love Katie Holmes find happiness for the sake of their children.

Hollywood.com reported her as saying: "I hope he's happy, it's that simple. If he's happy our kids are happy. He's had a few girlfriends now, and it's been years - we've moved on."

Kidman insists she has remained single even though Cruise has been involved with the likes of Penelope Cruz, Sofia Vergara and is now finally proposing to Holmes after a three-month whirlwind romance.

The couple have two adopted children, 12-year old Isabella and 10-year old Connor.
