Weisz, 42, who wed "Bond" star Daniel Craig in June 2011, said she never fantasised about her big day or wedding dress because she did not think it was something she would ever do, reported Showbiz spy.
"In my twenties I never imagined I would marry or be a mother. I didn't... You know... I think some young women imagine their wedding dress.
"I think it was an enjoyable idea. I just didn't have it because I was unmarriable in a Jane Austen kind of a way. There was a moment when I really thought I wanted to be a mother and I was surprised. It wasn't something I had thought about. I just think it was instinct," she said.
R&B star Rihanna and rapper Drake are leading the MTV Video Music Awards (VMA) nominations with five nods each.
