Richie was born in Berkeley, California, and has Mexican, Creole, and Spanish ancestry. Her biological father is Peter Michael Escovedo, a musician who briefly played with Lionel Richie, and her biological mother Karen Moss was the executive assistant for Nicole's aunt, Sheila E. When she was three, her parents agreed to let her move in with Brenda Harvey and Lionel Richie because they could not afford to provide for her financially. "My parents were friends with Lionel," she told People in 2003. "They trusted that they would be better able to provide for me."Initially, Lionel Richie became her guardian.
Brenda and Lionel legally adopted Nicole when she was nine.
