The singer allegedly threw a first-class temper tantrum when a United Airlines flight attendant simply asked the star what she wanted to drink. The attendant told Star Magazine, "I just said, 'What can I get you to drink?' But Jennifer refused to even acknowledge me. She turned her head away and told her personal assistant, 'Please tell him I'd like a Diet Coke and lime.'"

He went on to explain that Lopez refused to make eye contact with him, stating, "She wouldn't even look at me. It was sad, she seems so sweet in her movies." The actress's diva antics have made her notorious in the world of corporate flight attendants, where a slew of airline employees have alleged Jennifer does not permit female attendants to come onboard to work her flights.

"J. Lo won't let female flight attendants work. She brings her own male flight attendant who is not a flight attendant, but a 'personal assistant,'" one private attendant posted to @CFA_Life's Instagram. Countless aviation employees went on to share their own experiences of the singer's "cold and arrogant" behavior.

"After completely taking out everything in the drawers to fill them with all her preferred items, I was told I had to fly home because she didn't want a female flight attendant... only to have to come back and Uber to the airplane and reset my items, because it was only a one-way flight," claimed another flight attendant who had the unfortunate luck to be assigned to Jennifer's flight.

One anonymous Instagram user went as far to allege that J. Lo harbors a strong resentment toward female flight attendants specifically, stating, "She hates flight attendants because her ex-husband Marc Anthony had an affair with one when they were married." A source told Us Weekly that Anthony hooked up with a flight attendant he met aboard a private plane in 2009.

"Marc and Jennifer almost split up over it, Jennifer was going to leave him then, but Marc begged her to stay. They went to marriage counseling and she decided to give it another shot. He was someone she truly loved," the source told Us Weekly.

The jaw-dropping accusations of Lopez's abhorrent behavior did not sit well with fans, with one user saying they "can never look at her the same way again, whether it's in real life or on-screen."
