At some point in his life, Corey became a hugely famous pop star with many fans.
Following the Fall of the Angels, the angel Thaddeus took Corey as his vessel and took over Corey's life as a pop star. Thaddeus was eventually tracked down by the angel Gadreel while he was possessing hunter Sam Winchester. Gadreel killed both Thaddeus and Corey with an angel blade both on Metatron's orders and to get revenge for Thaddeus' treatment of Gadreel and Abner.
