The actress - who has two children, daughter Ava, 11, and seven-year-old son Deacon with ex-husband Ryan Phillippe - gets the greatest pleasure in her life from her family and would love it to grow in the future.
The 34-year-old actress - who is currently dating Hollywood agent Jim Toth - said: "I would love to have more kids. Kids are the best part of my day. I don't wake up to make movies. I wake up to hang out with my family."
The blonde beauty - who has previously dated actor Jake Gyllenhaal - also claims it isn't easier dating someone who isn't famous, but insists she feels very "comfortable" in her relationship with Jim.
When asked about the differences between dating a famous man and a non-celebrity, she told the January 2011 issue of America's Glamour magazine: "I have a little perspective on this. I wouldn't say it's easier. Every relationship has its own dynamic. And I don't want to disparage any of the other relationships that I've had that were meaningful and wonderful. But what I'm finding out is that it's very comfortable to be with somebody who understands my career, but doesn't do what I do. He's a great guy. He's wonderful."
Although she is getting older, Reese insists she feels sexier than ever because she is so comfortable with herself.
She explained: "I think as a woman, you get older, you feel more confident in your sexuality. You're not as intimidated by it, not as embarrassed by it. Sexuality and femininity is an accumulation of age and wisdom and comfort in your own skin.
"I feel better - so much better now than I ever did in my 20s. I am calmer; I know who I am. And as a result, I feel much sexier. There's always going to be somebody younger or sexier. That's why I like to say, and it's become my famous line, 'Funny doesn't sag.'"
