Seth Rogen won't sign prenup

Seth Rogen won't sign a prenuptial agreement before getting married.

The 'Green Hornet' star insists he has no intention of drawing up legal documents to protect his fortune before he ties the knot with his fiancee Lauren Miller later this year.

The comic actor was pushed on the subject during an appearance on DJ Howard Stern's radio show.

When quizzed by the shock jock on whether or not he was going to get a prenup, he said: "I'm not. My business manager told me to get one."

Stern then told Seth how 'Frasier' star Kelsey Grammer is going to have to hand over around $50 million to his ex-wife Camille in their divorce settlement.

But despite the warnings, he replied: "Marriage can be expensive and if I lose millions then it'll be the best millions I've spent."

Although he was happy to discuss his opinions on prenups, the 28-year-old actor is remaining tight-lipped on his wedding plans.

Seth revealed his friend Jonah Hill and his 'Pineapple Express' co-star James Franco will be among the guests but he won't reveal the date beforehand.

He said: "I don't want to say the date because of the paparazzi."

Seth and Lauren - who have been together since 2004 - got engaged in September and he claims the ring is "the most expensive thing" he's ever held in his hands.
