JULIA LOUIS-DREYFUS is funny AND sexy. And she puts both of those attributes to work for her in a new spread for "GQ" in which she HAS SEX WITH A CLOWN ... then gives birth to a CLOWN BABY. It's a classic ... and somehow, the picture of the CLOWN COITUS is way more erotic than it has any right to be ... even with Julia wearing a CLOWN NOSE.
