At Michael Rubin’s Fourth of July Party, Jennifer Lopez seemed angry with Beyoncé.

A source told OK! magazine that JLo and Beyoncé’s husbands, Ben Affleck and Jay-Z, came with them to the Hamptons event. But the first one was said to be angry that everyone was looking at Love On Top singer.

“They exchanged pleasantries then kept a total distance,” the source said when asked about their relationship.

The person said, “Everyone was basically fawning over Beyoncé and making more of a fuss over her than Jennifer — she’s always felt competitive toward her.”

A source says that JLo didn’t like it when Ben was seen paying his respects to the hit-maker of “Irreplaceable.”

“Ben started kissing up when Jennifer’s back was turned. Things got increasingly awkward as the hours went by,” the person said.

It’s important to note that this is not the first time the Hustlers star has had a public fight with a fellow musician.

OK! wrote earlier about how Mariah Carey and JLo have been fighting for a long time.

Mariah said in an interview in 2018: “I really was trying to say something nice or say nothing at all. I really was. I try to stay away from it because you can’t drown in that. I don’t know how people read comments all the time and then survive.

Back in 2016, when Mariah was asked about Jennifer, she said, “I am very forgetful. Apparently, I am forgetful because I don’t remember the fact that it was just like, ‘Hi, I’m so and so.’”
