Bwahahaha! This has to be the funniest video I've seen in a while! Jeremih was caught lip syncing at a recent show, and his fans weren't having that!

Here's the most recent update from this story as he tries to defend himself by saying he wasn't lip syncing!

According to Jeremih, the situation wasn't ideal regardless -- because the promoters didn't adequately prepare the stage or provide the right equipment for J to perform.

Jeremih tells us, he was late on stage because the crew wasn't ready for him to perform -- but the crowd was chanting his name anyway ... so he decided to make do with what he could.

Big mistake -- because Jeremih says the equipment backfired ... playing his vocal track much louder than he wanted ... making it look like he was trying to lip sync, when he wasn't.

As for the bottle attack -- Jeremih says a girl threw her underwear at him and the girl's boyfriend got jealous, hurling a bottle at Jeremih in retaliation. Jeremih walked off soon after.

LOL!! What a lame excuse! He was CLEARLY lip syncing and there is no excuse for it-- he didn't have to hit any high notes in 'Down on Me'! #NOSHADE just truth  @MoniqueDee_
