Lively, 25, who recently tied the knot with Reynolds in secret, said she wanted to have a big family with him, reported Ace Showbiz.
"Right now, I'm so peaceful. I've never been happier in my life. It's the choice that you have to wake up every day and say, 'There's no reason today can't be the best day of my life'. I've always wanted a big family. Oh, I'd love 30 (children) if I could," she said.
Lively, who has maintained lean figure, also said that she does not avoid comfort food when it comes to bringing happiness.
"That means being open to experiences and not getting caught up in typical Hollywood obsessions - like compulsively managing one's weight.
"I obviously have plenty of imperfections on my body, but I'd rather have a little bit of cellulite and go do a food trip and try every ice cream place in the South."
