11:49 AM PT -- Sources close to the situation tell TMZ ... the party followed COVID-19 safety guidelines with less than 100 people in attendance. The state's health department recommends gatherings of no more than 250 attendees. For what it's worth ... Florida Gov. Ron DeSantis reportedly hosted a GOP backyard party last weekend in the Gov's mansion for roughly 50 guests.
As for Teyana's party ... we're told there was a mask mandate but people took them off for pics. They say having the party completely outdoors was also a safety guideline it followed.
Teyana Taylor's gotta be feeling appreciated today ... she celebrated her 30th birthday with a flashy Miami shindig, packed with her celeb friends.
The newly-retired singer danced her ass off Wednesday night at the bash ... surrounded by folks like Diddy, Lil Wayne and A$AP Ferg, just to name a few. You can see in the video ... people were shoulder-to-shoulder at times on the dance floor.
Unclear what, if any, testing went down beforehand -- but there was no social distancing and very few face masks.
Also worth noting, there are very few COVID restrictions right now in Florida.
The party, sponsored by the clothing line Pretty Little Thing, came less than a week after Teyana announced she was retiring from music because she felt underappreciated by the industry.
She said, "I’m retiring this chapter of my story with the comfort that I can depart with peace of mind seeing that all the hard work & passion put was indeed loved & supported somewhere in the world!"
She definitely got love and support to ring in the big 3-0.
