Diddy‘s latest accuser says his career opportunity of a lifetime turned into a horrific night … where he was drugged and sexually assaulted by Diddy … TMZ has learned.

An anonymous man says he was an up and coming rapper/singer in 2015, when he landed a nightclub gig in L.A., and Diddy showed up with his entourage and a ton of Ciroc bottles for the crowd … according to a lawsuit filed Monday by attorney Tony Buzbee.

The John Doe accuser says one of Diddy’s associates told him if he did well, Diddy would talk to him about possibly signing with Bad Boy Records. After his performance, he claims he was invited to a VIP section with Diddy and other “well-known” artists, many of whom were taking drugs.

Corey Holcomb swears he got sucker punched by a female comedian who’s hell-bent on taking him down, physically and financially … so he’s seeking court-ordered protection.

Corey says the comic-on-comic beef started back in December outside the Hollywood Improv … when Cristina Payne put hands on him as his back was turned to her. In the docs, filed Monday in L.A. Superior Court, Corey also claims she hurled a bunch of insults and obscenities worthy of a celebrity roast.

Among the comments Cristina allegedly made — “Your mother is a bitch,” and “Your d*** ain’t s***. That’s why your wrist got broke.” For the record, Corey says his wrist injury was from skateboarding … not masturbation.

Now, in his request for a restraining order against Cristina, Corey also claims she provided TMZ with a video that only shows part of their altercation … excluding her aggression. While it’s true TMZ broke the story about Cristina’s allegation Corey struck her that night, we were never given, nor did we post, a video of their fight.

Congratulations are in order for J.J. Watt and his wife, Kealia … the couple just announced they’re expecting their second child!!

The Watts dropped the big news Monday afternoon … showing off the former National Women’s Soccer League player’s baby bump as their son, Koa, gave it a peck.

There is no word yet on the gender or the due date for the little bundle of joy … but they are all smiles in the photos dropping the news!!

“Can’t wait to welcome new love into our lives,” J.J. said on social media.

The couple welcomed their first child together in October 2022 — after tying the knot in February 2020.

J.J. announced his retirement from the NFL in December 2022 … after dominating the league for 12 seasons.

His brothers T.J. and Derek Watt have yet to react to the post … but we imagine they got an inside scoop well before the public did.

Watt’s huge following was quick to share their excitement over the news … and given the little one’s parents, we take it there’s a bright future in sports if they decide to go that route!!
