Cassie's bombshell lawsuit against Puff Daddy alleges he was very jealous of her when he wasn't paying men to have sex with her.

He allegedly blew up Kid Cudi's car when Cudi and Cassie started dating.

According to Shy Glizzy's bodyguard, Ant Glizzy, Diddy also went Suge Knight on Wale because he thought he was flirting with Cassie in the studio. [Jump to 8 minutes.]

"I swear for God, [there's] a balcony in the studio," Ant said.  "They got Wale over top his face, hanging out the balcony.  I can't really hear with they saying.  We knew it was him because we knew what kind of shoes he wore to the studio."

According to Ant, Wale didn't realize that he and Shy could see that Diddy and his goons were dangling him.  So he said it was just a big misunderstanding and that they resolved it.

But given Cassie's lawsuit, Ant decided it was time to say what really happened.
