50 Cent isn't the only one celebrating the downfall of Puff Daddy.

The Diddler's old artist, Mase, is also taking a victory lap after the Feds raided Puff's home in search of evidence of sex trafficking.

"Reparations is getting closer and closer," Mase said, addressing the weekend's big news.  "Give me a percentage.  The big payback."

He was then told the raid took place on the 27th anniversary of Biggie Small's Life After Death album.

"Is this amazing that all of this would transpire on that day," Mase said.

Would Big also be cheering Diddy's demise if he was still alive?
