OT Genasis’ birthday celebrations came under fire when police officers showed up with their guns drawn.

It was completely wrong and unnecessary. Read on to get all the tea spilling on OT Genasis birthday celebrations RUINED by police…

CelebNMusic247.com has learned via a report from TMZ that police officers with their guns drawn shut down OT Genasis’ birthday celebrations because of a reported gun threat.

OT Genasis was celebrating the big 3-1 a few days early at Pinz in Studio City, with friends like Miguel, Tamar Braxton, and Nelly.

Studio City happens to be a bit on the White side of things. Anyways, Law enforcement sources tell us someone called police late in the night to report two people at the party were flashing guns and threatening each other. That got cops to the alley in a hurry, locked and loaded.

As you can see, officers came prepared with shotguns and a massive police presence. A helicopter was even called in for the potential threat. We’re told police searched the premises and even detained a few people still inside … but no weapons were found.

That got cops to the alley in a hurry, locked and loaded, Meanwhile, OT Genasis was clueless – it appeared to be relatively peaceful and joyous, with people singing “Happy Birthday” to O.T. and having a good time. One party attendee tells us they didn’t even notice the cops until the party started to wrap up. – TMZ

More evidence proved that via that surveillance footage reviewed from Pinz did not show any of the guns that had been reported.

Watch – our favorite thing about the video is Tamar Braxton getting hood with it after singing happy birthday to OT Genasis. – Go Tamar!  You have to love Beyonce’s Coachella performance for breathing new life back into OT’s “Everybody Mad” song. Its the same song Tamar is going in on at the Birthday Bash. Check it:

Thankfully, nobody ended up being arrested.
