A$AP Mob co-founder A$AP Bari was involved in an all-out, no-holds-barred, royal rumble last night … and authorities are still trying to find out what caused the clash!!!

A rep for the Miami Beach PD tells TMZ Hip Hop … cops received a call from security guards for a “large fight” at Hotel Faena just after midnight Sunday … judging from the footage, the call was correct.

The fight appeared to contain about a dozen men — and one of them got Bari good as the video unfolded by grabbing him by the collarbone and throwing him in the bushes!!!

Our Miami Beach PD source tells us that by the time officers arrived on the scene, the two fight clubs had already dispersed and left the location.

W. Kamau Bell is ripping the Kennedy Center Honors … he says the only folks taking home hardware are celebs who are cool with President Trump … which is a problem for him, because he says Trump is a fascist.

The comedian and TV host joined us on “TMZ Live” Monday and took shots at the honorees from Sunday’s 48th Kennedy Center Honors.

Trump hosted and helped pick the honorees … including Sylvester Stallone, Gloria Gaynor, George Strait, and KISS.

While Bell says everyone who made the cut was talented, he says the main criterion was being down with Trump. We pushed back and said the same held true when Barack Obama was president … but Bell says the main difference is that Trump is a “dictator.”

Bell — who also got in jabs at Gloria and KISS — tells us he wouldn’t accept a Kennedy Center Honor during Trump’s presidency … he says there would be no way to accept the award without getting political.

Jessica Simpson ain’t one to quit … she’s giving her Hidden Hills, California crib another shot on the market — relisting it after a quick month-long timeout.

The singer’s trying to offload the 7-bedroom estate for a cool $17.9 mil — the same price she dropped it to back in January when she first tried to move it … smack in the middle of those L.A. wildfires tearing through the region.

Nearly a whole year’s passed, but the place must’ve kept some bad mojo ’cause it’s still struggled to sell … especially since Jessica first listed the mansion for $22 million back in September ’23, and it’s been fighting for a buyer ever since.
