The Simpsons is doubling down with an hour-long episode in January.

It will be the first time the half-hour animated series has expanded to a full hour, Fox said.

Al Jean, executive producer of the series that revels in daring humour, included a political shot in announcing the episode.

"I just pray it won't be the last thing people see before a Trump inauguration," Jean said in a statement.

Taraji P Henson, who plays Cookie on Fox's Empire, and Keegan-Michael Key will guest star.

Henson voices Praline, the former wife of a music mogul who has conned Mr. Burns into bankruptcy.

Key voices a rapper, Jazzy James, who joins with Praline, Homer and Bart to help Mr Burns seek revenge.

The airdate for the episode, titled The Great Phatsby, a play on the classic The Great Gatsby, was not announced.

The Simpsons begins its 28th season on September 25, and will reach its 600-episode milestone October 16.
