Rapper 50 Cent is fuming after discovering his new Robin Thicke collaboration has been leaked online. The song, Follow My Lead, and its accompanying video, which features movie star Dustin Hoffman, made its debut on select websites on Thursday night (09Aug07), according to MTV News. According to a source, the song, which features on 50's upcoming album Curtis, wasn't supposed to be released until later this year (07) or early in 2008. The same source tells MTV that the rapper "erupted" upon hearing the news, "ripping out a plasma TV, throwing his cell phone through a glass window and saying that he was going on vacation." By late Friday (10Aug07) morning, the Follow My Lead clip had been removed from YouTube.com, but high-quality video clips could be found elsewhere on the Internet when WENN went to press. Hoffman plays 50's psychiatrist trying to persuade the rapper to stop using derogatory words in his songs in the quirky video.
