We are all very aware of the fact that Charlie Sheen is an absolutely outspoken and sometimes disrespectful individual. The actor is always saying something off the wall and extremely controversial like his recent comments about Donald Trump.

It appears that the actor has more to say now, and the subject of those comments is none other than mega-star Rihanna. Just to refresh your memory, Charlie Sheen and Rihanna got into it on Twitter a few years back because of an incident that happened in 2014 at an LA restaurant between Charlie, his girlfriend and the singer. Long story short, Charlie's girlfriend wanted to meet Rihanna but the singer allegedly blew them off and that angered the actor.

Charlie posted the following rant to Twitter.

so, I took my gal out to dinner last night with her best friends for her Bday. we heard Rihanna was present as well. I sent a request over to her table to introduce my fiancé Scotty to her, as she is a huge fan. (personally I couldn’t pick her out of a line-up at gunpoint) well, the word we received back was that there were too many paps outside and it just wasn’t possible at this time. At this time? AT THIS TIME?? lemme guess, we’re to reschedule another random 11 million to 1 encounter with her some other night…? no biggie for me; it would have been 84 interminable seconds of chugging Draino and “please kill me now” that I’d never get back. My Gal, however, was NOT OK with it. Nice impression you left behind, Bday or not. 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. 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. clearly we have NOTHING in common when it comes to respect for those who’ve gone before you. I’m guessing you needed those precious 84 seconds to situate that bad wig before you left the restaurant.

Rihanna clapped back accordingly with the following tweets.

While several years have passed since the incident, it appears that Charlie is still sour about it and voiced his opinion on the matter in a new interview on the Bravo network show "Watch What Happen Next?" In the clip below the actor gives the singer a few choice words and seemingly reignites the long standing feud. While there is no response from the singer yet, ain't no telling what type of storm will be brewing because of this.
