Actress Krysten Ritter just finished filming How to Make Love to a Woman, based on a best-selling novel by adult film star Jenna Jameson—someone whom Ritter admires. “It’s not like I’m sitting at home watching porn or anything,” she says. “[But] I have a lot of respect for women who make their own destiny.” That’s not to say Ritter has plans to follow in Jameson’s footsteps: The actress fought to show as little skin as possible in her upcoming film.

Just for the record, Ritter isn’t related to the late John Ritter. “My agent gets that question about once a week,” says the 26-year-old, who was raised far away from Hollywood on a beef farm in rural Pennsylvania. Instead, Ritter has made it all on her own—scoring a coveted role opposite Isla Fisher in Confessions of a Shopaholic, which hits theaters February 13.

Based on Sophie Kinsella’s book series of the same name, Confessions stars Fisher as Becky Bloomwood, a recent college grad with a penchant for overspending. Ritter plays Bloomwood’s pal and roommate, Suze, alongside Hugh Dancy, Joan Cusack and Kristin Scott Thomas.

THE PRICE IS RIGHT: Unlike the main character in Confessions, Ritter claims to be a conservative consumer—except when it comes to beauty products. “I’ll spend hundreds and hundreds of dollars at Sephora,” admits the actress. “I’m not proud of that.”

ON THE BAND WAGON: When she’s not on set, she can be found on stage, playing guitar for pop band Ex Vivian. “I’m always thinking of schemes to make a quick buck,” says Ritter, who has been known to record songs in hotel bathrooms while on location. But the actress doesn’t have plans to quit her day job anytime soon. “My first priority is acting, and that’s where I make my money.”
