LOS ANGELES (Reuters) - It is not quite official, but it is pretty close. Singing star Jennifer Lopez will return as a judge on top-rated TV singing contest American Idol, the programs lead producer said on Wednesday. Executive Producer Nigel Lythgoe, in an interview on American Idol host Ryan Seacrests radio show, was asked whether Lopez would return for an 11th season, and he said yes. I believe were still waiting for the official announcements, but Im delighted to say that all three judges, along with the brilliant host of 'American Idol, is back for the next season, Lythgoe told Seacrest. Lopez returns to join longtime Idol judge Randy Jackson and rocker Steven Tyler, the Aerosmith frontman. Her decision to rejoin the No. 1-rated U.S. TV show has been the source of much speculation in Hollywood since the singer said earlier this summer that she was undecided. Indeed, just last week at a meeting of television critics in Los Angeles, top programing executives for the Fox network, which airs Idol, were tight-lipped on the subject.
