Jennifer Lopez is not oblivious about what her 18-year age difference with boyfriend Casper Smart could mean for their future together.

J.Lo tells People for their cover story this week how Casper, 25, helped [her] heal after her divorce from Marc Anthony. However, for the first time the Dance Again singer acknowledges she has doubts at times about their relationship.

"I ask him, 'Why don't you go find a young girlfriend and get out of here? What do you want with me?' And you think, 'How long is this gone be?' You think, 'Okay, in 10 years I'm going to be like this and you're going to be like that' and men at that age are I think all different things, Lopez, 43, tells the mag. The truth is we don't know what's going to happen. We're loving this moment right now. We make each other happy."

Lopezs relationship with Casper certainly isnt her first romance to make headlines. The Parker actress was of course once engaged to Ben Affleck and infamously dated Diddy.

"I don't regret those things that's who I am," Jennifer says about her high-profile relationships. "But at least now I'm at a point where I have to recognize that these choices and things that happen are partly because of me and my decisions and I have to be more careful. So I am being more careful."

The Golden Globe Awards could have posed a potentially awkward situation for Lopez, with three exes Affleck, Diddy, and Bradley Cooper all in attendance. But the singer says on The Ellen DeGeneres Show in an interview set to air Wednesday that she was unfazed by it all.

I see them a lot, J.Lo responds when asked whether it was awkward to all be in the same room. Were in the same business. We run in the same circles.

Lopez even gave Affleck a standing ovation when he took home the prize for Best Director for Argo.

It was a great movie. And, we got you know, a lot of like they were really hard on us in the press when we dated back in the day. On movies and things like that, Lopez continued. So it was a nice moment. It was a nice to see him have that moment. I was really happy for him.

Lopez has certainly has a lot of topics on her mind leading up to the release of her new film, Parker, co-starring Jason Statham, out January 25. With the new season of American Idol beginning tonight, she admits to a bit of nostalgia about her former judges chair. I am going to miss it, she tells DeGeneres. I love what I am doing but I am going to miss it. I just had a good time. I love the people there, Randy, Ryan, Steven, Nigel everybody behind the scenes everybody. It was a nice little family.

Speaking of family, Jennifer also expressed that shed indeed like to have more kids one day soon. "I would love to have more," J.Lo exclusively told E!s Marc Malkin. "I don't know if it's in the cards for me, but I would love it."
