Lady Gaga stunned U.S. TV viewers on Saturday night (16Nov13) by simulating sex with R. Kelly. While guest hosting Saturday Night Live, the pop star performed Do What U Want with the soul star and during their TV get together she pretended to give Kelly oral sex and then he lay on top of her. Gaga also poked fun at the controversy linked to her alleged song similarities to Madonna by performing Born This Way as the Material Girl's Express Yourself in a skit about an album of awful cover versions. Madonna fuelled the drama onstage during her MDNA tour last year (13) when she sang a snippet of Born This Way during performances of Express Yourself. Lady Gaga also took a trip to the future in another sketch, pretending to be herself in the year 2063. As a washed-up has-been, the elderly pop star attempted to convince a maintenance man in her apartment building she was once a big name.
