Watch out, Julia Roberts. Here comes … um … Jenna Jameson?

Best known as the Queen of Porn, host of Playboy TV’s “Jenna's American Sex Star” reality show and a member of the X-Rated Critics Organization Halls of Fame, Jameson apparently is going legit.

Last seen in the quasi-horror satire “Zombie Strippers,” she’s actually heading into rom-com territory for “How to Make Love to a Woman” -- in which she stars opposite some real actors: Josh Meyers (“That ‘70s Show,” “MADtv”), Krysten Ritter (“Confessions of a Shopaholic”), Ian Somerhalder (“Lost”) and James Kyson Lee (“Heroes”).
 
Meyers plays a successful career man who can’t bring his girlfriend, played by Ritter, to orgasm. Jameson’s the “world’s most famous porn star” who’s brought in to help.

OK, so it’s not much of a stretch. But here’s the trailer -- and it's only on TheWrap.

Oh, and we should mention -- the trailer ends with the tagline: COMING  too SOON.
