Lopez finds `American Idol` hard to work on

London: Singer Jennifer Lopez will reprise her role as a judge on the "American Idol" and says that the singing reality show is "hard" to work on.

For the 42-year-old, it was tough to deal with the talent show in her first season, but it did not put her off returning for another season. "It`s so funny because I was such a fan of the show in the beginning, so I thought I pretty much knew what the show entailed," a website quoted Lopez as saying. "I discovered that live TV is tiring so that was a big thing. That`s why I marvel at (host) Ryan Seacrest. When I think about how he gets up at three in the morning, I think, `If he can do it, I can do it`. But we still have fun. We have amazing talent so that always makes it exciting," she added. IANS
