'X-Men' Director Bryan Singer -- Shower My Baby ... With Presents!

"X-Men" director Bryan Singer was gleeful Sunday, as he attended a baby shower for what will be his new son.

Singer is having the baby with longtime friend Michelle Clunie ... whom Singer says he once dated. They plan on raising the baby together and he even bought her a home just a few houses down from him in West Hollywood.

Singer's an advocate for having babies this way ... hopefully it will end up better than the Clay Aiken situation. He's at war with his former friend/baby mama Jaymes Foster.

As for the sex of Singer's baby ... he was mum but his friend may have blown Singer's cover as they walked into the party.
