Soapy hip hop drama Empire will get even more star-studded in season two as Chris Rock, Lenny Kravitz and Alicia Keys all make guest appearances.

Fox announced the trio of superstar guests during its Upfronts presentation in New York City yesterday, May 11.

Empire started as a mid-season replacement for Fox earlier this year, and currently airs on E4 on this side of the Atlantic, but its initial success has guaranteed an expanded second season of 18 episodes.

Empire co-creator Lee Daniels previously revealed that the show's second run will also include guest appearances from Oprah Winfrey and rapper and actor Common.

The King Lear-like show centres on a record label boss (Terrence Howard as Lucious Lyon) who is battling with his ex-wife (Taraji P Henson as Cookie Lyon) and their three sons over control of the business.

Empire continues tonight (Tuesday) on E4.
