Grey DeLisle was born in Fort Ord, California. She is a singer and well-known voice actress. She was raised by her grandmother through her difficult childhood because her mother was a drug addict. Her grandmother was a singer and performed often with Tito Puente. Grey was highly interested in goth bands, mostly The Cure. Her mother, however, born-again Pentecostal, strictly forbade Grey to listen to goth music. In her late teens, she sang gospel songs. Thanks to that, she became interested in stand-up comedy and started to perform it. She also had a talent for voice impressions, which led to voice acting.DeLisle started in a few animation series and, since then, has been featured in numerous video games.She is best-known for her sinister voice of the evil sister "Vicky" in the Nickelodeon TV series, "Fairly OddParents" (2001-2013), as well as the equally evil "Mandy" in the Cartoon Network TV show, "The Grim Adventures of Billy and Mandy" (2001 - 2007).
