Mariah Carey made an unexpected appearance on her son’s Twitch live stream … and the poor kid was mortified in the hilarious moment!

The 13-year-old Moroccan, AKA “Rocky,” was chopping it up with his fans on Twitch … when his sister Monroe showed up in the background — followed by his superstar mom.

Needless to say, everyone on his stream went nuts when they saw Mariah … with several asking “Ms. Carey” to stick around and hang.

For those unaware, Rocky and Monroe are the twins Mariah shares with Nick Cannon — part of Nick’s LARGE family tree.

Odds are Rocky will lock the door next time before he is ready to game on!

UFC’s Henry Cejudo is a great fighter … and he is also a great neighbor ’cause he recently helped stop a hit-and-run suspect in his hood.

Here’s the deal … a speeding car crashed into the house right next door to Henry’s in Phoenix last night — and the visuals are wild!

The UFC star gave an interview shortly afterward … and he said the driver of the car was going to book it after the crash and his neighbor tried to stop him, which is when the dude punched the neighbor.

It’s a miracle no one was seriously hurt at the scene … although the suspect is likely pretty damn sore!

Henry is the former Flyweight and Bantamweight Champion … and was at one time the youngest American Olympic gold medalist in wrestling history, winning the Summer Olympics in 2008.

Terrence Howard just gave a glimpse into what he said was the dark side of Hollywood … and one example he used from his personal experience was none other than Diddy!

The film and TV actor was a recent guest on Patrick Bet-David‘s “PBD Podcast” … where he claimed he was targeted by Diddy for sex under the guise of coaching.

TH doesn’t say exactly when this alleged attempt by Diddy occurred … but claims he was invited to Diddy’s place when the music mogul asked Terrence for acting lessons.
