Ill-behaved grandmother and 90 Day Fiance villain Angela Deem is now terrorizing airline staff.

A new video has surfaced in which she is berating a flight attendant in a tone usually reserved for her husband and in-laws.

We would love to say that this is just an unfortunate lookalike.

However, there is audio. We would recognize Angela’s dulcet tones anywhere.

Angela Deem is a deeply toxic person with limited emotional intelligence and poor conflict-resolution skills.

Actually, she might be secretly very good at resolving conflicts … but she would rather create them.

For years, 90 Day Fiance viewers have watched with horror as she terrorizes Michael Ilesanmi and his in-laws.

Some find Angela funny.

Others recognize that there is nothing funny about emotional or verbal abuse.

And others think that her repulsive behavior is all an elaborate act put on for reality TV.

Folks … Angela is not that good of an actor. She’s not even a convincing liar — watch any scene where she tries.

Her latest tantrum could not conceivably have been for the benefit of reality TV cameras.

However, she was caught on video by a fellow airplane passenger.

In a video circulating on social media, Angela appears standing up on an airplane, presumably during boarding.

We can see her messy blonde bun. Her voice is jarringly familiar as she berates a flight attendant.

“You are not gonna talk to me like this,” she then menaces.

Angela insists that the attending is “not the law enforcement,” whatever that means.

She then instructs the attendant to “get who you need to get.”

Angela accuses this overworked and underappreciated employee of being the one who “started this s–t.”

Angela turns around and seems to ask if anyone has seen hear earphone bud — at least, that is the guess.

Reportedly, she then voluntarily departed the plane.

As you can imagine, commenters were cracking jokes left and right.

We can only assume that Angela saw a “no smoking” sign and ignored it.

All joking aside, we do not yet know what caused all of this commotion.

Well, Angela caused it. But we don’t know what the specific topic was, this time.

90 Day Fiance fans have seen this behavior many times.

Angela is both rude and crude.

At times, she does not seem to fully realize that other people have their own feelings.

Usually, Angela directs her insults at Michael.

Her on-again, off-again husband has endured a lot of emotional abuse.

We would love to believe that they are broken up.

However, these two have reconciled many times.

For reasons known only to him, he often takes her back.

They fight. Then they split. They reconcile. Then they fight again. It’s a toxic cycle.

At the moment, fans do not actually know if they are together. That is on purpose.

Rumors say that Angela and Michael will appear on a future season.

NDAs prevent them from sharing their status for now.
