Renner, 43, said fatherhood is the best thing in life, reported E!Online.
"She's kind of ruined my life. We were talking about how much I love my job and all these wonderful things-that means nothing any more. Now I know what real love is, what real existence is. Best thing that I've experienced in my life," she said.
Last month, Renner revealed that he had secretly married his longtime girlfriend Sonni Pacheco, who is also the mother to his one-year-old daughter.
