Today on Tyra Banks' show, Moment of Truth host Mark L. Walberg, who's bringing his lie detecting equipment! Tyra takes the test! They ask if she's jealous of Oprah, and, while managing to call Oprah old, she says no! Of course that's a huge, honking lie! Oh, Tyra, young self-obsessed person that you are. What better life is there for you to covet than someone who started off cheesy (though, not as cheesy as your America's Next Top Model), and became IMPORTANT. Poor Tyra, so desperately wanting money. And a school in Africa. And cultural cachet. A sad, plain truth has been laid bare. Video after the jump.
