Seth Rogen: 'I Once Peed' While Parked On Tom Cruise's Driveway (VIDEO)

Seth Rogen is tweeting for charity until Jan. 13 and since the actor joined the microblogging site he's revealed more than his share of strange and funny stories.

"I once peed in a Snapple bottle in my car while parked in Tom Cruise's driveway," he tweeted on Jan. 2 and later explained why, while chanting with radio host Howard Stern on Monday.

"It's true," Rogen confirmed. "Years ago Tom Cruise was viewed as a psychopath. It was during this time that he, very wisely, thought to align himself with comedians. He was meeting with people like me and [director] Judd Apatow, to kind of, I think, get a sense of the comedic landscape at the time. So me and Judd had a few meetings at his house," Rogen explained.

The 29-year-old star said he had showed up at Cruise's house early and he had a long driveway and didn't want to go in, so instead of using the movie star's facilities he relieved himself in an empty bottle. "I was so uncomfortable, I had never met him before. It was so weird," he said of not wanting to go into Cruise's home alone.

Rogen also tweeted a few more true tales from Hollywood, admitting that "While trying to park at a party a few months ago, I smashed into @JonahHill 's car. I still haven't fixed it." And he tweeted, "I went to a strange party on shrooms. Ron Rifkin was there, and I was freaking out because I thought he was Wolf Blitzer."

Rogen told Stern, "That really freaked us out because we thought he was on [shrooms] too. And we were like f**k this is a big deal ... We thought we uncovered a major story,"

The actor is currently in negotiations with Sony to finance and distribute a film "The Apocalypse," written by himself and his "Superbad" co-writer Evan Goldberg, that would mark Rogen's directorial debut.
