KARRUECHE CALLS CHRIS BROWN AN HYPOCRITE AND TELLS HIM TO STOP THE THREATS

  I reported here today how Chris Brown and his friend threatened to kill an artist for flirting with his ex. His ex, Karrueche has responded to his threats read below.

Karrueche is done with Chris Brown's possessiveness and his henchman's violent threats ... and she's firing back.

Chris' ex is responding to a threat made by a member of Chris' posse ... a threat directed at Marques Houston, who gave thumbs up to the pic she posted of her amazing body.

The threat was in the form of a photo of 2 guns, with the caption, "Niggas sho no how to disrespect, I don't care if they not still together."

Karrueche thinks it's time for Chris, and any of his friends, to get over it -- "I'm bored and tried of this situation. I don't get it because I'm single."

She adds, "I thought we have all matured and moved on. Especially since Chris has been seen with multiple women since the breakup. I don't want anything to do with any type of violence or negativity."

Karrueche tells us she and Marques are just friends, nothing more. The two of them just finished filming a movie together.

Chris has been radio silent since the threat was posted.
