Jennifer Lopez is single again.

No wonder I've been getting those late night phone calls.

The "American Idol" judge dumped boyfriend Casper Smart after about two and a half years of dating, according to E! News.

"They were hoping to be more low key about things," a source told the website. "He was slowly going to move out and that would be it."

Right. It was his decision. Of course.

A rep for Lopez declined to comment to E!.

Maybe she was busy auditioning new "dancers."

Lopez met the dancer-choreographer shortly after she and ex-husband Marc Anthony split up in the summer of 2011.

Even though they spent quality time together, Lopez never gave the public any indication she would turn the much-younger Smart into Mr. Lopez No. 4.

"I'm one of those people who does not like to be alone," Lopez, 44, said at Idol's Winter TCA panel in January. "I have no shame saying that at this point in my life. I think we have to own who we are."

Right. Which explains why she's calling me ... again.

Asked if she would marry again, Lopez said, "I don't know, I don't know, we'll see. I always believed in that institution. My parents were married for a very long time, for 35 years. I believe in it. It's difficult. I've had my challenges, but at the same time I believe in love. That's the main thing."
