When Stormy Daniels first appeared in the headlines claiming to have an affair with America's current president, many may have been shocked. There was one person however who wasn't shocked at all, considering he already knew.

Seth Rogen recently appeared on the beloved Ellen DeGeneres Show where he admitted that Stormy Daniels spoke of her intimate time with Donald Trump 10 years ago when she had minor roles in his films Knocked Up and The 40-Year-Old Virgin.

"I've known Stormy Daniels a long time, and I'll be honest, she may have mentioned some of this stuff around 10 years ago," he told Ellen and the audience. "At the time, when you ask a porn star who they've been sleeping with and they say Donald Trump, it was like the least surprising thing she could have said.

He continued: "Again, at the time it wasn't that surprising and then as his campaign rolled out, it became clear that no one cared about anything he did, so it didn't really occur to me even that it would come out or anyone would care about it. Then when I saw it, I was like 'Oh yeah! Stormy told us all about that.'"
