Michael Jackson

Michael Jackson  

Today would have been Michael Jackson's 55th birthday. Though the King of Pop died four years ago at the age of 50, Twitter was full of birthday greetings and retrospectives of the late singer.

Also, producer Timbaland hinted at a new project that could include Jackson's vocals. In a teaser initially posted on YouTube's Revolt TV channel, Timbaland talked about being approached by Epic Records executive L.A. Reid about a project that "would be like two kings working together." Timbaland never mentions Jackson's name, but the singer's image appears throughout the clip, which has appeared in several third-party versions since the original was removed from YouTube.
