Born Anne Marie Fletcher in Detroit, Michigan, Fletcher lived with her family in the local lakefront suburb of St. Clair Shores, Michigan until her 1984 graduation with honors from Lake Shore High School. Fletcher began taking dance lessons at a local dance studio, Turning Point School of the Performing Arts, at age 12 after watching her mother take a dance class. At age 15, she appeared in the local show Salute to the Superstars at the now-defunct Mr. F’s Beef & Bourbon dinner club in Sterling Heights, Michigan. Upon graduation from high school, Fletcher moved to Los Angeles, California, where she attained further training and began working as a professional dancer; including performing as a Laker Girl.
