Cudi, whose real name is Scott Mescudi, took to the stand on the ninth day of Diddy's sex-trafficking trial in Manhattan.

During the second week of Sean 'Diddy' Combs' sex trafficking and racketeering trial, Kid Cudi testified about Cassie Ventura and an alleged arson.

Cudi detailed a series of disturbing incidents — including a 2012 Molotov cocktail attack on his Porsche and a break-in at his Hollywood Hills home — both of which he believes Diddy orchestrated. Following him taking the stand, Young Thug weighed in online, labeling Cudi a “rat” in a now-deleted post.
