Has she one-upped herself again?

Lady Gaga has worn a meat dress, a mermaid tail -- and now she's posing as a man for the cover of her latest single, "You and I." Specifically, the man is Joe Calderone -- Gaga's male alter-ego.

Gaga Tweeted the pics, saying, "'You will never find what you are looking for in love, if you don’t love yourself." The song is about Gaga's reconciliation with ex Luc Carl last year, but they have since split again.
