A big mazel tov to Seth Rogen! While fans were hitting up the movie theaters this weekend to see his film "50/50," Rogen was busy marrying his longtime lady love, Lauren Miller.

People.com reports that a number of Rogen's pals and former co-stars, including Jonah Hill, Adam Sandler and Paul Rudd, attended the California ceremony on Saturday. The pair married in Sonoma in a location overlooking a nearby vineyard.

A female rabbi married the pair with other friends like "Knocked Up" director Judd Apatow, his actress wife Leslie Mann and "The Office" star Craig Robinson in attendance. After the pair tied the knot they reportedly drove off in a convertible to another location for the A-list reception.

A source tells Usmagazine.com that "the wedding was more laughs than anything else. Every other line was a joke and the crowd couldn't contain their laughter. It was nonstop fun!" The festivities reportedly took place over three days.

Rogen's cancer dramedy, "50/50," co-starring Joseph Gordon-Levitt, opened on Friday and came in at a solid #4, right behind "Dolphin Tale" (#1), "Moneyball" (#2) and "The Lion King" (#3).

Rogen and his writer bride met back in 2004 when he was a writer on "Da Ali G Show." When he was on "Conan" last November he opened up about popping the question to Miller a couple months before, in September.

"Literally, I felt like someone had given me like a truckload of heroin to hold onto, I felt like the feds were going to kick in my door at any second," he said of buying the engagement ring. "I couldn't have a conversation with my girlfriend. All I could think of was this ring. Like, 'Don't say 'Lord of the Rings'! Don't mention anything about a ring!"

He joked that the proposal wasn't perfect: He did it while she was dressing. "I didn't picture it like this, and I know she didn't picture it like this," he recalled. "No little girl is like 'It'll happen in a closet with my [chest] out.' "
