The 25-year-old model - who is in a relationship with actor Jason Statham - thinks her career is "very self-indulgent" and she is looking forward to reaching a point where she wants to shift her focus to other people instead.
She told the new issue of Britain`s Elle magazine: "I always see myself working, but definitely being a mum will be a big part of me. Look, I think my career is very self-indulgent. It`s all about me.
"I`m not a doctor, I`m not looking after people, I`m not saving children. I`m in the entertainment business. I`m a model. I`m an actress. So it is very self-involved and I think there is naturally a point where you think, `I don`t care about myself as number one any more.` I want to care about other things."
Rosie also admitted she "hated" modelling when she first began her career.
She explained: "I wasn`t quite tall enough either and I hated it, to be honest. There was no individuality, no opportunity to be individuals.
"I think that people forget you`re human and you just become an object. In New York, I was constantly reminded that I wasn`t right wherever I went and that was difficult because I`d come from a place where it didn`t matter."
