Remember when Farrah Abraham said she made $1 million off of her "sex tape" (read: her porno) with James Deen? Turns out, she made maybe 1/100th of that.

Fox411 did a pretty thorough investigation on the price of celebrity sex tapes, and it's estimated that Abraham only pocketed about $10,000 for 'Back Door Teen Mom,' not the mil she swears by.

Sex tape broker Kevin Blatt revealed, "Tami Erin [the star of 'Pippi Longstocking] was offered $10K up front which is standard for Vivid. It is what they offer every celebrity, not a million dollars."

He explained, "Paris and Kim made millions, but that's because it was a different time. People bought DVDs then."

Another sex tape source added, "In reality she (Abraham) got $10,000 upfront and 30 percent of sales, minus the cost of production. The entire celebrity sex video genre is a lot of unsubstantiated marketing with very little truth behind it … It's all publicity. It's all hype."
