Then: For a time, it seemed that singer Chris Brown could have been slated to take over for Michael Jackson as the standout triple threat singer, dancer and actor of his generation. Brown often emulated Jackson and even performed a tribute to him at a 2008 MTV Awards show. Brown told MTV that he and Jackson were often in contact, and that Jackson had called him for his birthday and discussed a duet. Now: Following an assault on girlfriend Rihanna, Brown fell out of favor with fans and has not commented publicly on Jackson's passing. He was reportedly kept out of the BET tribute to Jackson by fellow hip-hop star Jay-Z.
