Mom-to-be Nicole Kidman is about to give birth for the first time -- and she's getting support from good friend and fellow Aussie mom Naomi Watts!

"Whenever you're pregnant, you always call on your pregnant friends and compare notes," Watts shares with People magazine. "It's what happens in friendship."

Does Watts think that Kidman will make a good mother to baby number three? Kidman has two adopted children with ex Tom Cruise. "Of course," said Naomi, "she's already a great mum!"

Watts gave birth to son Alexander with actor Liev Schreiber last summer.
