They’ve always had a tumultuous relationship so it’s no wonder Chris Brownand Rihanna have been lobbing hurtful comments at each other on their social media accounts.

Last night (May 9) the “Don’t Wake Me Up” stud took to his Twitter page to post a snarky statement about his “We Found Love” ex.

Brown wrote, “She’s not mine if she’s everybody else’s,” thought to be a reply to Ri-Ri’s previously cranky words on Instagram.

Nevertheless, until these two resolve the issues between them, the Twitterverse could become a pretty tense place!
