The 27-year-old performer is dating film producer Reg Traviss and said she would like to be a mum in the not-too-distant future.
She said to UK's Glamour magazine: 'I'm of the age when you start thinking about it - not seriously - but you start thinking about having kids.
'Although I'm not going to be getting pregnant in the next nine months! I recently watched Toy Story 3 with my godson, Theo, who's five. It was really fun and I was running in and out getting more and more popcorn for us! But right now I'm happy to be the godmum or the fun auntie.'
