Mo'Nique Trashes Oprah, Tyler Perry, Tiffany Haddish on Shannon Sharpe Podcast

Mo'Nique is riding Katt Williams' coattails in talking major trash -- 'cause she basically just did the exact same thing on the same pod ... but her list of names slightly differs.

The comedian sat down for a new episode of Shannon Sharpe's "Club Shay Shay" podcast -- and she took aim at A LOT of big stars in the industry -- airing out grievances and claims against Oprah, Tyler Perry, Tiffany Haddish and Kevin Hart ... just to name a few.

Mo'Nique has been vocal over the past few years about feeling blackballed in Hollywood and she continued to double down on all that here in this chat with Shannon ... once again dragging O and Tyler into the conversation with allegations of them attempting to torpedo her career, something she's alleged in the past -- but there's a new twist to this now.

She tells Shannon that she has TP on audio allegedly admitting something to this effect ... and SS himself appears to acknowledge that he might have heard it off-camera.

We should note ... Tyler has denied tarnishing Mo'Nique's rep behind the scenes -- despite her repeated insistence over the years that he has. She also didn't play the alleged audio on Shannon's show. Mo'Nique wasn't done there, though!

She kept the parade of insults and accusations going -- calling out Oprah for "overstepping" with her in many instances ... and even took a shot at Tiffany for something she said about Mo'Nique in a GQ interview. Mo'Nique went below the belt and mentioned TH's DUI arrests, as well as her controversy in regard to the icky lawsuit she was embroiled in.

We will note ... Mo'Nique has been on this campaign for years and years now -- alleging she's been done dirty by so many different people in the industry ... and while she's squashed some of her beef with a few individuals, it sounds like there's still bad blood with a vast majority.

It's pretty crazy to think Mo'Nique's gripes all stem from a movie she did way back in '09 -- a film we're sure she probably regrets now considering how much acrimony it's spurred.
