“Mad Families” actor Charlie Sheen revived his feud with “Work” singer Rihanna during a Wednesday stint on “Watch What Happens Live” with host Andy Cohen. Sheen confirmed he and the Barbadian beauty never made up, even though their fight happened via Twitter nearly three years ago.

“Oh, that b----,” Sheen, 51, said when he was asked about making up with Rihanna, “No, no, no.”

Cohen claimed Sheen’s insult made their feud worse, but the actor brushed it off. “No, she abandoned common courtesy and common sense,” Sheen noted.

The drama started when Sheen asked if his then-fiancée, Brett Rossi, could meet Rihanna. They were all eating at the same restaurant. The singer refused, saying there were too many photographers outside the eatery.

With Rossi slighted, Sheen went on one of his famous Twitter rants. “See ya on the way down...and actually, it was a pleasure NOT meeting you. Clearly we have NOTHING in common when it comes to respect for those who've gone before you,” he tweeted at the time. “I'm guessing you needed those precious 84 seconds to situate that bad wig before you left the restaurant.”

“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,” he added. “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!”

RiRi responded to the 2014 diss by changing her Twitter photo to a picture of her signing an autograph for a fan. She made sure to add a picture of Sheen’s head to the body.

The singer, 28, hasn’t responded to Sheen’s latest diss.

He promoted his appearance on the Bravo series by sharing a quote from Vanilla Ice’s hit, “Ice, Ice Baby.”

Sheen’s new movie, “Mad Families,” premiered Friday in theaters nationwide.
