Miley Cyrus is no Adam Lambert ... at least according to "Good Morning America."
After simulating a girl-on-girl kiss while on "Britain's Got Talent" two weeks ago (bottom left), the 17-year-old pop sensation performed on 'GMA' today (top).
Interesting move ... considering they banned Adam Lambert from performing back in November after he kissed a male band member on the American Music Awards (bottom right).
Translation: Heterosexual underage female singer simulating a lesbian kiss = good. Gay male singer actually kissing a man = bad.
