Playing a mom in her new film The Truth About Emanuel stirred up some maternal instincts for Jessica Biel.
“Every woman has some kind of intuition of how they’d interact with a child,” she told PEOPLE at the Los Angeles premiere of the film on Wednesday.
“I feel comfortable around kids, so I was kind of rolling with that idea,” the actress admits.
Wearing a two-piece lace skirt and cropped top by Giambattista Valli topped with a leather jacket, Biel, 31, – who married Justin Timberlake in a romantic Italian ceremony in October 2012 – says she’s open to having kids of her own, but she hasn’t put a deadline on it.
“I’m not sure about sooner or later,” she said. “But definitely at some point.”
