In a ruling issued Thursday, U.S. District Judge Jed. S. Rakoff dismissed "finally and with prejudice" 21 of the 22 causes of action in the lengthy lawsuit that alleged Combs sexually harassed Rivers and stroked her breasts during production of the hit MTV reality show, which started filming in 2002.

The R&B singer and podcaster, formerly a member of Bad Boy Entertainment group Da Band, sued the music mogul in January, accusing him of sexual harassment, assault, and overseeing "inhumane" work conditions. In one instance, Rivers accused Diddy of groping her breast while both were in a hallway.
