Patrick, who is introduced as the number one porn star in the world, will appear on the show decked out in her Mistress Couture lingerie line.
Patrick also gets to show off her vocal range as she serenades Daly with her rendition of Hopelessly Devoted to You from “Grease.”
"It's Valentines, a day for romance," Patrick said. "And what better way to celebrate than with sexy lingerie and show tunes."
