Sandra Bullock would like to have more children.

The 49-year-old actress - who split from husband Jesse James in 2010 - has three-year-old adopted son, Louis, and would be open to expanding their family if the tiny tot is happy to share his home with some siblings.

She told the Daily Mirror: 'If all of a sudden my house had eight kids in it, if it was OK with Louis and it felt like a good safe family, I would be fine with that. It would be because that is what my home is for. So it is up to him. He is the boss of the house so I have to abide by his rules.'

Bullock thinks motherhood has made her more emotional and claims she gets 'weepy all the time'.

Quizzed on what has surprised her since becoming a mother, she said: 'Oh, how much of an emotional mess I become at anything. I thought I was the most hardened, jaded individual I knew, and now I can be brought to a mess within seconds. I just get weepy all the time. It is embarrassing. We will be talking with friends and they will be like, 'What's wrong?' And I'll be going, 'No, I'm happy!' '
