Charlize Theron is giving her son's old clothes to Chris Hemsworth.

The 36-year-old actress - who adopted six-month-old Jackson in March - is planning to donate the little boy's outgrown garments to her 'Snow White and the Huntsman' co-star or his two-week-old daughter India.

She said: "I'm going to give Chris' daughter all my son's hand me downs."

The 'Prometheus' star - who has been single since splitting from her partner of nine years, Stuart Townsend, in 2010 - has become "really creative" since becoming a mother, and she is amazed that she hasn't been as relaxed about work as she expected since welcoming Jackson into her life.

She added to BANG Showbiz: "I'm about to go and shoot the new 'Mad Max' film soon and when I heard that my son was coming in to my life I thought, 'I'm not going to want to go and make this movie, I'm just going to want to stay at home in my pyjamas and roll around on the carpet with him' and I did that for a few months and it was great, but the crazy thing that I wasn't expecting is that it made me feel really creative.

"I started developing ideas like crazy, selling movies through my production company and the more I think about 'Mad Max' the more excited I am. This little tiny baby has made me more creative and curious about the human condition so it's great."
