Big Sean is reportedly not happy after video of his ex-girlfriend Ariana Grande kissing her rumored new beau and playing a disrespectful prank (while yelling out offensive remarks) hit the Internet.

See What Big Sean Had To Say About His Split With Ariana Grande

An insider told Hollywood Life Tuesday that Big Sean thought the footage of Grande and one of her background dancers Ricky Alvarez was “immature” and “rude.”

“Sean saw the video and is both embarrassed and disappointed with Ariana’s behavior, especially with how she treated the worker. He says he would never disrespect someone that way.”

They added that he had a few thoughts for Alvarez as well.

“The fact that her new boy toy laughs along is quite telling. He think the whole incident was immature and rude.”

In the clip, Grande and Ricky Alvarez not only lock lips at Wolfee’s Donuts in Lake Elsinore, Calif., but lick some of the donuts that are set out for customers to purchase. But things take an even worse turn when a worker in the store brings out their orders.

It might be safe to say Grande and Alvarez didn’t know the security cameras existed or were even rolling during their excursion over the weekend.

Grande yelled out, “What is that?! I hate Americans. I hate America.”

The publication also noted that the owner of the shop, Joe Marin, wants Grande to apologize.

She has already issued a public apology via Twitter with a lengthy letter. She added that she is aware she has to be a better role model for her fans who admire her.
