Los Angeles, CAEven in a world of over-the-counter paternity tests, there are those who ask, “Who’s your daddy?” On November 29, Zero Tolerance Entertainment goes back to its gonzo roots for the answer in Who's Your Daddy 13.

Over the years, the Who's Your Daddy series has featured some of the biggest name stars in adult like Bree Olson, Alexis Texas and Jenna Haze. Melanie Rios leads the cast of this latest edition, which continues the classic theme of girls with “daddy issues” who perform wild sexual favors for their favorite “daddies.” This is the first volume of this series to come out in four years, signaling a return for Zero Tolerance to its primary focus, which made it one of the top gonzo companies in adult entertainment.

"We're excited to get back to what people loved about Zero Tolerance when we first launched the company — straight up hardcore sex shot gonzo style with really hot girls," said director Mike Quasar. "Who's Your Daddy is one of our best-selling titles, and fans have been asking when the next one is coming out, so we're happy to deliver this new volume now, full of incredible talent and some really intense scenes."

To coincide with the film's release, Zero Tolerance will host a contest for the "Best Daddy." To win a phone call from one of the stars, as well as the outfit that Melanie Rios wears in the film, fans can send an e-mail saying why they deserve to be the best daddy, or nominate someone else. All contest information will be posted on the company website.
