I want to know the answer to the following question:
What show did Simon Cowell join after leaving American Idol?
All the background I'm provided with is that "Jimmy Iovine, chairman of the Interscope Geffen A&M label group, the new partner of American Idol, acted as the in-house mentor in place of weekly guest mentors, although in later episodes special guest mentors such as Beyoncé, will.i.am and Lady Gaga were brought in.". Is that enough to answer the question?
Answer: no
