Sandra Bullock Adopted Son Louis in January 2010

Sandra Bullock is reportedly set to adopt another child.

The Oscar-winning actress adopted her little boy Louis in January 2010 when he was just a baby and is said to have already completed the paperwork for another child, although the process could take at least 18 months.

A source told RadarOnline.com: ''Sandra has always planned to have more than one child. She feels that now is a good time for a new baby to be welcomed into the family.

''Louis is a little young to understand that he is going to be a big brother, but Sandy is trying to get him ready for the transition. It took her about 18 months to finally get Louis, and there is no time table as to when she will get the second child. Sandy's adoption lawyer has told her it could take up to a year to complete the process. She doesn't care whether or not it's a boy or girl. She just wants a healthy a baby.''

Sandra originally started the adoption process of Louis with ex-husband Jesse James but eventually applied as a single parent after they separated following revelations he cheated on her with a string of women and the actress says the two year old has changed her life for the better.

She said: ''It's made me a better person. I really appreciate where I am.

''Everything becomes richer or more important or more frightening or more challenging. Everything becomes far more emotional, which I'm grateful for.''
