"The wedding was more laughs than anything else," one guest told the magazine. "Every other line was a joke and the crowd couldn't contain their laughter. It was nonstop fun!"

Rogen, 29, proposed to Miller, a writer, last fall. He shared the story on Conan about shocking Miller with the ring while she was undressed.

Rogen's latest film, 50/50, opened Friday to strong reviews but weak box office.
