On Wednesday night, Elton was right in the middle of Saturday Night's Alright (For Fighting) during his Caesars Palace concert when what appeared to be leftover Mardi Gras beads came flying over his piano.
The headliner was angry and surprised as he checked his teeth for damage.
TMZ was told that Elton had just invited the first row to come on stage, and one of those people was the bead-tosser.
Another concert-goer posted video singing along with Elton and stopped the clip in horror when the beads came flying at his face.
“A very stupid man strikes Elton with a necklace, he could throw away anything,” the fan wrote, along with video of the encounter.
