Apollonia, best known as a singer-actor-model and Prince protege who co-starred in the 1984 film “Purple Rain,” has taken the late singer’s estate to court over its attempts to cancel her trademarks and claim ownership over the stage name.

Actress, singer and former Prince confidante Patty Kotero, better known as Apollonia, sued the late rock star's estate in California federal court on Tuesday, seeking a court order that she owns the rights to the "Apollonia" name.

More than 40 years ago, Apollonia Kotero met Prince when she auditioned to play his love interest in 1984’s Purple Rain. She landed the part, and he named the character in the semi-autobiographical musical film after her.
