Nic & Naomi Swap Baby Tips

Naomi Watts has been sharing baby tips with Nicole Kidman.

The 39-year-old King Kong – who has a son with her partner Scream actor Liev Schreiber - actress has revealed: "Whenever you're pregnant, you always call on your pregnant friends and compare notes."

"It's what happens in friendship."

However, Naomi doesn’t think she will need much help as 40-year-old Nicole - who's expecting her first child with husband Keith Urban – already has two adopted children with ex-husband Tom Cruise.

Naomi added: "Of course she’ll be a great mother! She's already a great mum."
