Speaking to Ellen DeGeneres on an episode of her daytime chatshow, airing Friday, Lopez revealed that he hopes to have a large family, reports US Weekly.
"I definitely want more kids. I'd love three or four to be honest," admitted the former Saved by the Bell star, who welcomed a baby daughter with girlfriend Courtney Mazza in September.
Speaking about Mazza's reaction to his family plans, Lopez explained: "She's cool with that. She definitely wants them, but I kind of want them right away and that's where we have our differences.
"I think it's cool when the brothers and sisters [are close in age]. I was raised close in age. When there is too much of a gap... I don't know, I just think it would be cooler."
When asked if he and Mazza plan to get married, Lopez joked that the "jury is still out" on whether she wants to keep him.
