Actor says he doesn't know her well enough
The actor, 47, says he’s not close enough to the actress and her husband Keith Urban, 40, to take on the role.
‘I see Nicole probably once a year at a party or something,’ he tells OK!
‘I love her. She’s terrific, but it’s not like we are dear friends.
‘I read [the reports] and I can’t remember the whole article but it was hysterically funny.’
Nicole, 40, gave birth to Sunday Rose on 7 July.
She is already mum to adopted children Isabella, 15, and Connor, 13, with ex husband Tom Cruise, 45.
