If you can't beat 'em, join 'em. That's apparently the motto of former Hills antagonist Heidi Montag. Although she first denied the existence of the sex tape that estranged husband Spencer Pratt was supposedly shopping around, she's now changed her tune and is open to discussion, according to TMZ. Montag, who has always prided herself on her Christian values and pure image, is not willing to become a pawn in the celebrity porn industry... if the price is right. The heavily renovated reality star is prepared to sit down and talk numbers with Vivid Entertainment head honcho Steve Hirsch. In addition to the footage of her and Pratt, there's also supposedly some XXX scenes with Playboy Playmate Karissa Shannon. Before she's ready to pen a deal, Montag wants to see some figures around the Kim Kardashian film released by Vivid. Yesterday TMZ reported that Pratt stood to collect as much as $5 million for the sex tapes. Of course, like anything involving Speidi, Hirsch may just be another victim of one very well thought out hoax. TMZ is reporting that Hirsch will have a sit-down with Hirsch sometime next week.
