Latest: Hip-hop producer Timbaland has reignited his feud with ex-collaborator Scott Storch, after reportedly calling the Canadian beatmaker a "b***h" at a Justin Timberlake concert after-party.

Timbaland, who has worked with Nelly Furtado and Shawn 'Jay-Z' Carter, shocked a crowd of clubbers when he allegedly jumped on stage and yelled "Scott Storch is a b***h!" at club Marquee in New York, according to PageSix.

The dispute began over the Timberlake single Cry Me A River, which Storch claims to have partly produced but is only credited as playing the piano.
