Does the sentence "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 Beyonce, will.i.am and Lady Gaga were brought in." provide a valid answer to the question "Who replace weekly mentors as a more permanent mentor on American Idols tenth season?"
yes
