Jennifer Lopez isn't sure how to define her relationship status.

The singer, who split from Casper Smart last year, is seeing him again, but can't explain exactly what's going on.

"Have you ever been at a point in your life where you don't know? Like, you're not sure about things?" she said during a visit to "The Ellen DeGeneres Show."

"I am not sure about anything."

Lopez, 45, was first linked to the back-up dancer back in 2011, shortly after she separated from her ex-husband, Mark Anthony. Now, she said, they're "having fun" spending time together.

"I'm a grown woman," she told DeGeneres. "[I'm] doing ... whatever I feel like doing!"

Smart is on board, she added. She also said that if she were to get pregnant right now, she'd be thrilled, as she'd love to add to her brood. (Lopez has two children with Anthony.)

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