Charlie Sheen is still beefing with Rihanna

After feuding with Rihanna three years ago, Charlie Sheen still has beef with the "Work" singer.

During his recent appearance on Bravo's Watch What Happens Live, Sheen was asked whether he was able to reconcile his differences with Rihanna. In 2014, he claimed that the singer denied him and his then-fiance Brett Rossi the opportunity of meeting her while out at a Los Angeles restaurant.

"Oh, that b---h," Sheen answered. "No, no, no. No, she abandoned common courtesy and common sense," he added.

After the alleged non-meeting with Rihanna, Sheen responded with a lengthy diatribe on Twitter.

"Sorry we're not KOOL enough to warrant a blessing from the Princess. (or in this case the Village idiot) you see THIS is the reason that I ALWAYS take the time," wrote Sheen at the time. "THIS is why I'm in this thing 31 awesome years. Good will and common courtesy, carefully established over time to exist radically in concert with a code of gratitude! See ya on the way down, (we always do) and actually, it was a pleasure NOT meeting you."

That prompted Rihanna to shade Sheen on her own Twitter account. "If that old queen don't get ha diapers out of a bunch...," she wrote.
