Another insider added, “There was a fight after she performed at the Super Bowl, and when she had an album-listening party in Miami two months ago, there was an issue.�

The second source revealed that Anthony refused to give a speech at Lopez’s album launch party.

She said, “They fight, sure, but everyone fights. They’re fine.�

Meanwhile, Jennifer Lopez was unimpressed by a magazine interview with her ex-boyfriend Sean 'Diddy' Combs' current partner Kim Porter, declaring the former model's criticisms of her were "not necessary".

In an October interview in America's Essence magazine, Porter blasted Combs' relationship with Lopez, declaring, "He fell for a booty and a smile" and admitted she used to tell the rapper he would return to her when he left "his little Puerto Rican girlfriend".

Porter admitted she was in contact with Combs every day of his relationship with Lopez and forbid him from letting their son Christian associate with the Latino beauty.

Porter said, "Does she look like the type that would want to play house and family with two little black kids? No."

When asked by the New York Post what she thought about Porter's comments, Lopez says, "I am not going to go there.

"Look, she knows what went on, I know what went on. And that is where we have to leave it. I am not going to discuss any of the details of that intimate relationship that I had with the public. It's just not that necessary."
