Minka Kelly is one of the most desirable women on the planet. But is she the star of a not yet released sex tape, as some reports claim?

A source tells In Touch that a video is being shopped around and features Minka and a (non-famous) ex-boyfriend. And porn industry giants like Vivid Entertainment are clamoring to get their hands on the tape.

Minka is best known for her role in Friday Night Lights – and for dating Yankees star Derek Jeter for three years until they split last August. She's graced the pages of countless men's magazines – but a NSFW peek at the beautiful brunette would be a total "blockbuster," says Vivid founder Steven Hirsch.

Hirsch, who has released infamous celebrity sex tapes of Paris Hilton, Kim Kardashian and Kendra Wilkinson, tells In Touch that a video starring Minka could be "our best-selling of all time,” Hirsch says. “It could be worth up to $10 million in its first year.”

Minka's reps did not respond to a request for comment.
