Seth Rogen
wasn't worried about his movie "50/50" doing well this weekend -- he was too busy getting married!

The actor, 29, and longtime girlfriend Lauren Miller, 30, tied the knot Sunday at Kunde Estate in Sonoma, CA, in front of a star-studded crowd including former co-stars Paul Rudd, Leslie Mann, Jonah Hill, Craig Robinson, Adam Sandler and director Judd Apatow.

The two met in 2004, when Rogen was just a staff writer on "The Ali G Show."

Congratulations! Check out a gallery of the two over the years above.
