Scarlett Johansson is planning to adopt after playing a fictional nanny in her new film and realising she's a natural mum. The actress is convinced she'd be a great mother and now has sudden plans to settle down and start a family. And Johansson claims she'll start by opening her home to an underprivileged child. She tells USA Today: "I would love to have kids. I haven't really figured it out yet (but) I can see having a kid or two, and I would like to adopt children. "I think I'm tender with children. I got along really well with them. They make me feel young, like you're nine years old again."
