"You never know" may just become Jennifer Lopez's new catchphrase.

During an appearance on Friday's Ellen DeGeneres Show, the American Idol judge spoke about the singing competition series coming to an end after its 15th season premieres in January -- and it's pretty obvious she doesn't want to believe it's really going away.

"It's not over till it's over. So I just feel like you never know," she told DeGeneres. "After the finale this week and you feel that moment. You remember why you love this show. It just gives opportunity where there is none, you know, and it’s about dreams. And it’s about everything that America is about."

And yet the show isn't the only part of her life that she has a never say never attitude about.

When DeGeneres asked her about those photos of her holding hands with her ex Casper Smart, she doesn't deny that she's not back with him.

"I'm kind of not, but I kind of am," the 45-year-old artist shared about being single.

"Have you ever been at a point in your life where you don't know? Like you're not sure about things?" she asked DeGeneres. "Well, that's all. I am not sure about anything."

You never know, J.Lo!

One thing she does know for sure is that she'll be performing in Las Vegas for the next couple of years. In January 2016, she'll headlining "JLO Vegas" at Planet Hollywood.

"You know it's like an entertainer's dream because you really get to create the show that you've always wanted there." J.Lo said. "They have amazing shows in Vegas there like Cirque du Soleil."

The shows have inspired her too. "I'm like, should I do magic? Should I disappear? Maybe I'll do like this and then I’ll have a new outfit on," she teased. "Maybe I'll swim. I don't know. I’m thinking how do I make my show fresh and exciting. It's like sky's the limit there."
