Jovovich, 38, has a six-year-old daughter, Ever, with Anderson and claims expanding her family is her top priority as she and husband don't want a huge age gap between her kids, reported Contactmusic.
"I want to have a baby and that is my number one priority.
If I don't do it now, it will get more difficult the older I get. Ever is always talking about how much she wants to be a big sister.
"I have to do it before she is too old to enjoy it. I don't have all the time in the world to think about it," she said.
