The first season of Empire thoroughly rocked our world, so we can't wait for season two, which returns on Sept. 23. The cast is back on set for production of the next instalment, and director/creator Lee Daniels just started sharing some images and footage from set, including this video with guest star Chris Rock and star Terrence Howard as Lucious Lyon. If you recall, Lucious is hauled off to prison in the explosive first season finale, so season two will bring us to Lucious's new digs in lockup. We're keeping an eye out for more juicy stuff from Empire season two, so watch the video below for your first look (and a funny story from Rock about what happened to him on day one). Oh, then listen to all these songs on loop again.
