If this doesn't make you a full-blown Sheerio, we don't know what will. Ed Sheeran joined Chris Brown in Las Vegas over the weekend for an awesome performance of Chris' smash hit "Loyal" ... and CRUSHED IT.

At first, the duo was just teasing the crowd, as Chris and Ed spit out a few of the song's lyrics a cappella. You know, casual.

But that was just beginning. Because then the music started to play, prompting Chris and Ed (Chred?) to perform the track full out. And Ed wasn't just singing ... he flawlessly executed Lil Wayne's rap verse too.

At some point during the night, Chris also helped Ed sing one of his own big hits: "Thinking Out Loud." And Trey Songz, Nelly & Jeremih were all there too. In other words, it was an EPIC night.
