(Cover) - EN Showbiz - Jennifer Lopez claims Steven Tyler hates it when wannabe singers perform Aerosmith songs on American Idol.

The pair have been on screen together as judges in the tenth series of the talent show since January, and appear to get on well together.

Jennifer says that Steven - who is famous for being lead singer of iconic US band Aerosmith - is great, yet finds it uncomfortable when performers try to wow him with efforts he has heard many times before.

"I dont think Steven likes it so much when people sing his songs. Or at least, it doesnt make him more endeared to the person," she told Look magazine.

However, the 41-year-old admits she is not as concerned when those at auditions choose her hits. Jennifer believes that this is a compliment, rather than an effort to destroy the tunes, although there are moments when it can get a bit close to the bone. "I dont care as much. When someone comes in and does a beautiful rendition of your song its really touching," she explained. "But when they come in and butcher it, then its a bit different." She says Cee Lo Green and Bruno Mars covers are most popular.

The gorgeous megastar revealed that she was scared because she has always had a cue when on television. American Idol is unscripted - judges respond to live performances so the star had to be calmed down by partner Marc Anthony over her fears.

"Its funny because this is the first time Ive ever been on TV without a script. I was terrified the night before the first live American Idol show," she said. "I was like, Oh my goodness, this is overwhelming! I woke up white as a ghost and I was like, Marc! Marc! He was like, Whats wrong? You look crazy! Even though I have been out there for so many years it is a totally different thing." (C) Cover Media
