Last week, the Two and a Half Men star appeared on Bravo's Watch What Happens Live, where host Andy Cohen asked a question from a fan: "Have you mended things with Rihanna?" Sheen looked confused, but Andy followed up with "You got in a little Twitter feud with her." The actor quickly recalled the 2014 social media feud, where he called the singer out for being too "cool" to talk to him and his then fiancée in public. "Oh, that b**ch," Sheen said. 

Previously, back when the two stars initially started their disagreement, Sheen tweeted at RiRi, saying "Sorry we're not KOOL enough to warrant a blessing from the Princess (or in this case the Village idiot)," amongst other offensive remarks. The "We Found Love" singer responded with a sly dig at his fiancée's old age.

Cohen and fellow guest Craig Robinson quickly expressed their disdain for Sheen's live, on-air remark. To make up for it, the actor sent out an apology tweet, tagging the pop star and all. Though Sheen's tweet reads more like a Haiku than anything else, he did invite Rihanna for a drink, and even included a heart emoji.
