Did you realize that Charlie Sheen once had a Twitter feud with Rihanna? Me neither! But it happened! In 2014, Sheen apparently took his girlfriend out to dinner in Santa Monica on her birthday when he found out that Rihanna was eating at the same restaurant. Sheen’s girlfriend was a fan, so Sheen sent a request for a quick meet-and-greet. Rihanna turned him down. Sheen was not happy about it, going into full-on Twitter rampage mode over the slight. Here’s a sample:

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.

Naturally, you can read the entire thing at TMZ. At the time, Rihanna’s only response was this:

If that old queen don't get ha diapers out of a bunch…

Sheen has not let it go. Recently, Sheen appeared on Andy Cohen’s Watch What Happens Live. Cohen asked him if he’d patched things up with Rihanna, and here’s his response:

Charlie Sheen, clearly, is an expert on matters of common sense.
