The 39-year-old actress, who will turn 40 in August, is not bothered about getting older and is happy that she will never be in her 20s again, reported Contactmusic.
"I do not worry about age. I never have. I could not wait to get into my 30s when I was in my 20s. I do not want to go back to being 20, it was torture," Diaz said.
The "There's Something About Mary" star will be next seen as a pregnant woman in her latest movie, "What To Expect When You're Expecting".
