Clive Owen and Naomi Watts at the New York world premiere of The International
Motherhood, take two! Naomi Watts
– who gave birth to second son
Samuel in December – says things are all much more relaxed the second time around.
"There is much less fear this time," Watts, 40, told PEOPLE at a reception celebrating the world premiere in New York of her new thriller, The International
. "You are much more old-hand at it."
Are there fewer nerves over such concerns as picking the right diapers?
"Oh yeah. Nothing is slaved over like it used to be," she said.
Before the lavish bash at the Guggenheim Museum, Watts – sans Liev Schreiber, the doting father
of Samuel and 1½-year-old Alexander – walked the premiere's red carpet alongside costar Clive Owen while wearing a black vintage pantsuit by Thierry Mugler.
"He cuts suits so beautifully," Watts said of the designer. "The fact that I have a waistline tonight is kind of mind-blowing. I've still got my baby weight!"
