I want to know the answer to the following question:
In which season of American Idol did Steven Tyler and Jennifer Lopez become judges?
All the background I'm provided with is that "Jennifer Lopez and Steven Tyler joined Randy Jackson as judges following the departures of Simon Cowell (who left to launch the U.S. version of The X Factor), Kara DioGuardi (whose contract was not renewed) and Ellen DeGeneres, while Nigel Lythgoe returned as executive producer.". Is that enough to answer the question?
Answer: no
