Do I Look Like Joan Rivers to You - Mariah Carey ?

Mariah Carey is back on the move, dining out, having fun and talking to photogs, but there's one thing she won't do ... "Fashion Police."

Mariah was leaving The Palm in Beverly Hills Thursday night when our photog mentioned there's yet another vacancy on the now-controversial show that Kathy Griffin just quit, 'cause it's too mean. The singer weighed in on the chances she'd fill the spot.

Gotta say ... Mariah's way more fun than she was when she was full-on married.
