(Reuters) - Adam Lambert (C) and dancers perform "For Your Entertainment" at the 2009 American Music Awards in Los Angeles, California, in this November 22, 2009 file photo. The "American Idol" runner-up defended his sexually-charged performance at the awards show on Sunday, saying his goal was to promote "artistic freedom" rather than upset the television audience. Millions of viewers saw Lambert simulate oral sex with a back-up dancer, plant a passionate kiss on the mouth of a male keyboard player and gesture to the audience with his middle finger during the closing act of the live music awards show.
