Byrne was born in Riverside, California to Mexican parents from Los Angeles. She is the youngest of nine children. As a teenager, she held various customer service jobs, working at a clothing store and hardware store, among other retail stores.
She began her career in the adult industry in 2004, when she answered an ad in the local newspaper for "adult models." Apparently though, the ad was somewhat misleading; it was an ad placed by T.L. Tycoon, an agent casting actresses in pornographic films. In a radio interview (AdultFYI Article) with "Wankus," host of the Los Angeles based Wanker Show she describes the experience and ensuing difficulties. She eventually decided to pursue a career in adult film and has been in nearly 200 movies since. Her first film was entitled Young Tight Latinas 6. Since then her films have seen her carry out anal sex scenes, deepthroat scenes, BDSM scenes, and bukkake scenes. She appeared on The Howard Stern Show in February of 2005 to promote her latest video release. She is also a dominatrix in San Francisco, California, working for a company called Cybernet (now Kink.com). Aside from modeling and adult films she likes to write lyrics for ballads, and has hopes of pursuing this as a possible career in the future. In 2005 Byrne won two Rog Awards Critics Choice for Best Female Performer and Best Newbie.
