Under the tutelage of hip-hop impresario Sean 'Diddy' Combs, Aubrey O'Day propelled herself to the top of the charts as the breakout star of the singing group Danity Kane. She was born Aubrey Morgan O'Day on Feb. 11, 1984 in San Francisco, CA and began performing at the age of four. Among her early acting roles, mostly in local stage productions, was Dorothy in "The Wizard of Oz" and Sandy in "Grease." After graduating in 2001 from La Quinta High School in La Quinta, CA, O'Day majored in political science and drama at the University of California - Irvine. The aspiring entertainer's life changed when she was handpicked by Combs to appear on MTV's "Making the Band 3" (2005-06), a reality series that followed the rap entrepreneur as he assembled a female singing group. Out of thousands who auditioned, O'Day was one of five young women who made the cut. Alongside fellow winners Dawn Richard, Wanita 'D Woods' Woodgett, Shannon Bex, and Aundrea Fimbres, O'Day launched her music career as a member of the pop/R&B group, Danity Kane.
