Lacie Heart (born August 22, 1986) is an American pornographic actress.
She grew up on a ranch in Templeton, California and studied ballet as a child. She danced at a Canoga Park strip club's amateur night at age 19 on a whim. While she was there she was recruited and subsequently met with agent Derek Hay of L.A. Direct Models in August 2005. Her first on-camera appearance was in a scene for Fantasy Wash with Jack Venice who had introduced her into the adult film business. She signed with Vivid in January 2006 and was with them for nearly a year. She was introduced to fellow performer Scott Nails at a party about a month after she had entered the business. They became a couple soon after. She left Vivid after she told them that the only guy she wished to work with on camera was Nails; Vivid already had one actress who did only girl-girl, and they did not care to have her signed to work exclusively with one guy. In December 2006, Lacie signed with Digital Playground. As of June 2007, she lives in Arizona and commutes to Los Angeles to film.
