“Matt, I want to kill you right now.”

These are the words Jennifer Lopez said to Matt Lauer on the “Today” show Monday morning, after he began quoting a Vanity Fair article where she discussed the reason behind her split from husband Marc Anthony.

“I didn’t steal your diary, this is from an interview,” Lauer said, while Lopez smiled nervously. “Everything I wanted to say about the divorce I said in that article,” she replied.

About a month after their split was announced, the singer told Vanity Fair, “Sometimes we don’t realize that we are compromising ourselves [in relationships]. To understand that a person is not good for you, or that that person is not treating you in the right way.”

Up to that point in the interview, Lopez had happily talked about her working relations with her estranged husband on their show, “Q’Viva: The Chosen.”

“Marc and I were friends before we got married,” Lopez told Lauer. “It is a passion project for us. Even though it has its difficult moments, it still a great thing that we’re doing.”

David Letterman did slightly better at getting Lopez to discuss why her marriage ended later that day on the “Late Show.”

On working with her soon-to-be ex (the divorce isn’t final yet), Lopez said, “It’s fun ... but it has its moments. The same things that we kind of [makes hand gestures that seem to indicate conflict] didn’t work sometimes come up.”

When Letterman pressed her to explain what kind of things she was referring to, Lopez said “communication” was one of them. “You’re talking, and you don’t agree on something. And then you’re like, ‘Oh, be quiet,’” Lopez added while laughing.

The lesson for any future Jennifer Lopez interviewer: Don’t quote J. Lo to J. Lo.
