While funnyman Kevin Hart may joke about himself a lot, he doesn't appreciate other people making fun of his work ethic.

The comedian and actor was a target, like several other stars including Angelina Jolie and Michael Fassbender, who were discussed in some unflattering email exchanges between Sony Pictures Entertainment executives. The emails were leaked as part of the large cyber hack of the entertainment studio by a group calling itself the Guardians of Peace.

In Hart's case, Sony exec Clint Culpepper reportedly called him a "whore" for asking for a larger paycheck for promoting the film "Think Like a Man Too" on his Twitter account, apart from his $3 million payment, E! News reports.

"I'm not saying he's a whore, but he's a whore," Culpepper wrote about Hart to Sony co-chairman Amy Pascal. "If he doesn't do his normal routine, his film will not open as well and his brand will appear diminished and he will, in fact, be f*****g himself because we have his next 2 immediate films."

Without naming the specific studio or executives he was calling out, Hart shared two Instagram posts with fans that seemed to be a response to Culpepper's remarks.

The first was a screenshot of an article that calls Hart "the moneymaker" and states that he is "arguably the hardest-working comic in showbiz." It also recounts the millions he's made in the past year and his upcoming projects.

The second post, which was slightly different, was a typed message that seemed to be written by Hart himself. "Knowing your self-worth is extremely important people," it reads. "I worked very hard to get where I am today. I look at myself as a brand and because of that I will never allow myself to be taking advantage of. I OWN MY BRAND...I MAKE SMART DECISIONS FOR MY BRAND....I PROTECT MY BRAND....which is why I'm able to brush ignorance off of my shoulder and continue to move forward. I refuse to be broken people...with that being said it's now time for me to get back to building this empire that I've always dreamed of!!!!"
