Seth Rogen Wedding: Actor Talks Secret Nuptials On 'Ellen'

Seth Rogen stopped by "The Ellen DeGeneres Show" to dish about his October wedding to his longtime girlfriend, Lauren Miller, and explain why he kept the nuptials a secret from the public.

"I didn't want to say I was getting married on TV, because I think I overestimated my fame, and thought that it would be like an event -- and there would be helicopters and people camped out, but that didn't happen at all," said the actor, who is best known for his roles in "Superbad" and "Knocked Up."

"I can't sell these pictures to anyone. No one cares. And my dress was spectacular," Rogen joked on Friday's episode.

The couple wed in a vineyard ceremony in Sonoma County, California. According to Rogen, 275 guests attended. Among the wedding guests were Rogen's co-stars, including Jonah Hill, Adam Sandler and Paul Rudd.

Rogen met and began dating Miller, an actress and writer, in 2004. The pair announced their engagement in October 2010.
