Presenting: Mr. & Mrs. Duhamel!!!

We spotted Josh Duhamel and Fergie together for the first time since their super-secret wedding last night when they hit up the star-studded Vanity Fair party at West Hollywood's swanky Chateau Marmont.

Though it looks Fergie's still thinks it's her wedding night.  Or perhaps she thought it was a costume party and came dressed as a 'naughty bride'?

I mean, I understand the girl might be trying ot avert those post-wedding blues...but what about that concert tour she's got coming up and the baby Josh is so looking forward to??  Snap out of it, Ferg!
