Pete Davidson made a late change right before 'SNL' to mention Ariana Grande's name during this weekend's episode ... TMZ has learned.

8:15 AM PT -- According to the report, Mac's assistant found him unresponsive on his bed in a "praying position" -- kneeling forward with his face resting on his knees. The assistant described him as already being "blue" during the 911 call.

Blac Chyna is dropping the single that proves her goal to become a rapper wasn't just a hip-hop pipe dream -- as some people thought.

The feud between 50 Cent and Floyd Mayweather is still going -- Fiddy just CLOWNED the boxer's newly announced fight, saying his opponent is more "Uber driver" than contender. 

Rich the Kid could be playing with fire, because he's not letting his recent beatdown by armed robbers stop him from shining with tons of ice, and no bodyguards in sight. 

Diddy's birthday celebrations got so out of control over the weekend, police had to shut down a wild rager at the music mogul's mansion. 

UPDATE:  8:10 AM PT -- The Atlanta PD tells TMZ, they responded to a "shots fired" at Sutton's home. Officers found him dead in his garage with multiple gunshot wounds. It now seems it was NOT a home invasion. Cops say Sutton was talking in the driveway with another man when the conversation escalated and he was shot. The suspect fled in a car.  

Angela Simmons says she's hurting bad in the wake of her baby daddy's murder.

Angela is reeling from the death of ex-fiance, Sutton Tennyson, who was shot and killed Saturday at his home. It appears his death was the result of a home invasion robbery.

Angela and Sutton have a 2-year-old son, Sutton Jr., and with that she took some solace, saying, "Thank you for leaving behind my greatest gift. I'm hurting. I'm numb."

Angela went on ... "Thank you for the outpouring of love everyone. I can't believe I'm even saying Rest in Peace Sutton. I promise to hold SJ down in every way I promise."

Sutton and Angela called off their engagement in 2017.

Sutton was 37. RIP.
