Eminem and Lady GagaEminem is up to his old celeb-bashing tricks in his new song 'A Kiss' with rapper-in-crime Royce da 5'9" -- and this time he takes aim at pop superstar Lady Gaga.

Together Em and Royce are the rap duo known as Bad Meets Evil, and the two live up to their name in a hard-hitting track from their 'Hell: The Sequel' EP.

In 'A Kiss,' Eminem calls out past rumors that suggested Lady Gaga was a hermaphrodite, suggesting she's not so much a "lady" at all. "Tell Lady Gaga she can quit her job at the post office / She's still a male lady," Em raps.

Apparently Eminem wont be getting "a kiss" from Gaga anytime soon.
