Casper Smart and Jennifer Lopez are rumored to be back together again, although neither has officially confirmed their relationship status. During a chat with Ellen DeGeneres on her show on Friday, J-Lo came as close as anyone has thus far to defining their relationship.

“Have you ever been at a point in your life where you don’t know? Like, you’re not sure about things?” Lopez asked Ellen. “I am not sure about anything.”

Jennifer Lopez was first linked to Casper Smart–one of her back-up dancers–back in 2011, not long after her split from husband Marc Anthony.

Of their relationship now–she does admit they’re ‘seeing’ each other–she says the two are ‘having fun’ spending time together.

“I’m a grown woman,” she told Ellen DeGeneres. “[I’m] doing … whatever I feel like doing!”

So what if she becomes pregnant while ‘having fun’ with Casper Smart?

Jennifer Lopez claims he’s ‘on board.’

She has two children with Marc Anthony and says she’d love to have more.

“I wish I could have four or five more,” she gushed. “I love kids, and I love the whole experience.”

While none of this answers questions about the prospective longevity of J-Lo’s relationship with Casper Smart, she must feel something concrete exists between them if becoming pregnant wouldn’t be detrimental.

Casper Smart is 28 years old. Jennifer Lopez is 45. How might parenting be for a couple with this kind of May-December romance?

Surely time will tell whether things work out for Casper Smart and Jennifer Lopez. She is sure to have way more time on her hands in a few months, as American Idol–on which she serves as a judge–has been cancelled following its January run.

Of course J-Lo has signed on for a Las Vegas residency, and rumor has it, Casper Smart might be her choreographer.
