Jennifer Lopez is ''kind of'' single.

The 45-year-old singer - who split form her toyboy boyfriend Casper Smart after two years of dating last June - hinted she may have reconciled with the 28-year-old dancer after she was spotted kissing him in late March.

When asked if she was single during her appearance on 'The Ellen DeGeneres Show' yesterday (15.05.15), Jennifer explained: ''Yeah, yeah. I'm kind of not, but I kind of am.

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

However, the blonde beauty insists she won't shy away from confirming she is in a relationship when the time is right.

She said: ''I'm a grown woman. I'll say it. I'll say, 'You know what, this is going down.' But right now I just feel like ... I am me.''

Meanwhile, the 'Booty' hitmaker is said to have grown closer than ever to Casper and has been spending most of her free time with the choreographer.

A source close to Jennifer, who has seven-year-old twins Max and Emme with ex-husband Marc Anthony, said: ''Jennifer and Casper just get each other. They have a wonderful working relationship and a wonderful real relationship! Plus, her kids love him. Jen and Casper spend all their free time with each other. They work together as well, so time together is plentiful. They like being with each other and find a lot of time to hang out with each other.''
