Jennifer Lopez wants to be pregnant again as she called being a mother the greatest blessing. The only question, however, is if her on-and-off boyfriend Casper Smart is going to be the daddy.

The "American Idol" judge appeared on "The Ellen DeGeneres Show" on My 15 and was asked if she's planning on expanding her family.

"I would love to have more kids," she said. "I love my kids I wish I could have four or five more."

If I got pregnant, I would be so excited," Jennifer Lopez added.

Things naturally turned to Casper Smart, the reported boyfriend of Jennifer Lopez and the "Jenny From the Block" hitmaker was quite coy in describing her relationship with her man.

When Ellen DeGeneres asked her if she's single, the "American Idol" judge replied, "I'm kinda not, I kinda am."

"Have you ever been on a point in your life where you don't know? Where you're not sure about anything? That's all. I am not sure about anything. [I'm just hanging out] and having fun and doing things whatever I feel like doing. I'm a grown woman," she added.

When asked if Casper Smart is alright with that setup, Jennifer Lopez said, "He's on the same page."

"Here's what I always say, when I have something really to say that's permanent, in a way that's really important that I feel I have to say something, [I will]," Jennifer Lopez said.

When asked by Ellen DeGeneres if she would consider adopting a baby, she replied, "Maybe."

Jennifer Lopez then explained her wish to be pregnant. "I really love kids and I love the whole experience. I'm such a heart creature, that's where I kind of operate from, so the fact that you get to love somebody unconditionally in that way and not care if they love you back... that relationship is the biggest blessing in the world. I wish I could do it a thousand times."
