George Clooney has claimed that Nicole Kidman will be a "perfect" mum.

The actress announced she was expecting a baby with husband Keith Urban earlier this week and her friend Clooney revealed at the Critics' Choice Awards he was "thrilled" for her.

He told People magazine: "I'm thrilled for her. She'll be a perfect mother. She'll be great. She'll be a tall mother."

Clooney became close friends with Kidman after they worked together on 1997's The Peacemaker.
