Similar to thousands of hopefuls before him, Nigel Lythgoe's American Idol journey has reportedly come to an end. Lythgoe has decided against executive producing Idol's upcoming eighth season, TMZ.com reported Monday. While a replacement has yet to be named, TMZ.com reported Lythgoe thinks it is time for someone else to serve as Idol executive producer along with Ken Warwick and Cecile Frot-Coutaz. He has also privately stated he is "not passionate about it anymore" as a reason for leaving the program, sources told TMZ.com. Lythgoe began working for Idol creator Simon Fuller's 19 Entertainment production company in 2001 and is currently the president of 19 Television. In addition to executive producing Idol -- which he has done since the Fox mega-hit premiered in June 2002 -- Lythgoe also co-created Fox's So You Think You Can Dance with Fuller. Now that Idol is apparently out of the picture the 59-year-old plans to focus more of his time and attention on So You Think You Can Dance, for which he serves as executive producer and lead judge. Lythgoe is also working on another "joint venture" with Fuller, TMZ.com reported.
