Cassie Ventura testified at P. Diddy's sex trafficking trial, alleging that the rapper brought Britney Spears and Dallas Austin to her 21st birthday party.

Cassie said: "Sean was there, and he brought Dallas Austin, Britney Spears. I think those were the two people that stand out to me." As seen in photos from the lavish bash, Paris Hilton also attended.
