The Dip It Low singer will play mad maid Magenta, who runs oddball, cross-dressing alien Dr. Frank N. Furter's spooky castle with her brother Riff Raff, played by actor Reeve Carney, while secretly plotting to return to their native planet of Transsexual.

Magenta was originally portrayed by Patricia Quinn in the 1975 cult movie musical, and although Milian has had success both as a recording artist and in various acting roles, this is her first time delving into a musical.

She joins an already star-studded cast, featuring Laverne Cox as Dr. Frank-N-Furter, as well as Victoria Justice, Ryan MCCartan, Adam Lambert and original Rocky Horror star Tim Curry, who will take on the role of the criminologist narrator.

High School Musical director Kenny Ortega is set to produce, direct and choreograph the new project, which will premiere this autumn (16).
