Paul Rudd smokes pot but James Franco doesn’t? Seth Rogen blows our mind

partake.

In a segment called “Spill The Herbal Tea,” show host Andy Cohen told Rogen, known for his on-screen stoner characters, that “I'm going to go through a list of your co-stars and celebrity friends, you tell me if you've blazed up with them or not.”

James Franco?

“This is really depressing for me to say ... I've never smoked weed with James Franco – because he doesn't smoke weed,” Rogen said.

“Oh my God! That's headline news!” Cohen exclaimed.

“That's why he's such a good actor!" Rogen said. “It's really sad, actually.”

Cohen kept throwing out names.

Paul Rudd, Rogen’s “Knocked Up” co-star? “Oh yeah, lots of times,” said Rogen.

Sarah Silverman? “Yes, many times.”

Snoop Dogg? “Yeah, actually I have!”

Barbra Streisand? “No, but we talked about it a lot. She smoked weed with Peter Sellers though. That's the craziest s#$% ever!”

Though Rogen said he’d never shared a joint with well-known user Willie Nelson, Cohen revealed that he had, once.

He said he was at a house party in New York when Nelson showed up and told him, “Hey, I have this huge cigar-sized joint.”

Said Rogen: “He's like 80 years old. I'd be afraid he'd start coughing and his whole insides would come out!”
