ET spoke with Hirsch on Tuesday at Vivid's offices in Los Angeles, and the porn producer opened up about the big-money offer.
"The fact that she's with somebody else who's famous, a celebrity -- Tyga, reminds me of the Kim/Ray-J coupling," Hirsch said, referring to the famous sex tape made by Kylie's half-sister Kim Kardashian. "I think it would do tremendously well."
As for Kim's 2003 sex tape
, Hirsch explained that it was the "most successful tape this company has ever done."
"[It's] probably the most successful tape in the history of the adult industry," Hirsch added. "It continues to sell -- every day online, thousands of people come to our site to check out Kim's tape."
However, Hirsch had some stipulations about that massive, multi-million dollar payday -- the tape would have to meet some requirements.
"One thing's for sure: it would have to be an explicit sex tape," Hirsch explained. "The tape would have to be about 60 minutes long -- that doesn't necessarily mean it's 60 minutes of actual sex, but there would have to be sex combined with other things."
"That's something we would discuss with her and make sure she's comfortable with it," Hirsch added.
While it seems unlikely that Kylie would take Hirsch up on his offer, she's not the only star the CEO would love to make a sex tape deal with.
"Angelina Jolie [and] Brad Pitt would be huge," Hirsch said. "A tape with George Clooney and his new wife would be amazing."
