Funnyman George Lopez has launched a scathing attack on Jay Leno, branding the chat show host "the worst interviewer on TV". Lopez has dubbed Leno "two faced" for failing to invite him onto THE TONIGHT SHOW since 2005 - despite pretending to be a good friend of the star on the phone, reports PageSix.com. He says, "Leno is the biggest two-faced dude in TV. When I had my transplant, he called me and was the nice guy on the phone. And then he just puts the knife in your back. It tells you something about Jay Leno if CONAN O BRIEN is coming into The Tonight Show when Jay Leno is still young enough to be the host. "The dude's, like, the worst interviewer on TV."
