During a sitdown interview with Esquire UK, the pop star became immediately bothered when the reporter brought up her recent professional reunion with Chris Brown, her ex-boyfriend who infamously abused her in 2009 during their relationship.

"Some people felt it sent the wrong message ... You'd gone back to someone who put you in the hospital," the journalist said, which struck an irritated chord with the Where Have You Been singer.

"Oh really? Did I?" Rihanna answered back. "Did I? Did I? Did I? ... Okay. In a completely professional environment. And on a complete professional note. I mean, if I went back to him [as a girlfriend], then that’s a whole different discussion ... I think a lot of people jumped to an assumption that was incorrect and they ended up looking stupid."

Instead of changing subjects to avoid any verbal altercations, the reporter pressed on with questions pertaining to the thin line between her professional and personal life. That's when Rihanna decided to fight back.

"This is turning into a tacky interview," Rihanna said. "What do you really want to talk about? I’m not here to [talk] about messy s**t ... It upsets me that you keep asking the same kind of questions about stuff that’s trivial. What’s there to talk about? Are all your questions like that?"

Yes, if you didn't know, RiRi IS capable of such a fierce response! Looks like this journalist might have learned his lesson on proper interview etiquette!
