Stormy Daniels apparently told Seth Rogen about her alleged affair with Donald Trump '10 years ago'

Seth Rogen has apparently known about Stormy Daniels' alleged affair with Donald Trump for nearly 10 years.

During an appearance on "The Ellen DeGeneres Show" that aired on Monday, the actor revealed that Daniels, who actually appeared in "Knocked Up" and "The 40-Year-Old Virgin," shared details of her alleged tryst with him about a decade ago.

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

"So, yeah, she did mention it," he added.

Daniels alleges that she had an affair with the future president back in 2006. "The 40-Year-Old Virgin" was released in 2005, while "Knocked Up" was released in 2007.

"Again it wasn't -- at the time -- wasn't that surprising and then, as [Trump's] campaign rolled out, it became clear that no one cared about anything he did," Rogen went on. "So, it didn't really occur to me that it would come out or that anyone would care about it. But then, when I saw it, I was like, 'Oh, yeah, Stormy told us all about that.'"

"I haven't seen Stormy in years, but she's clearly done well with herself," he added with a laugh.

Rogen went on to explain that Daniels played a stripper in both of the popular movies.
