Shelby Corcoran
A character on Glee, namely the biological mother of Rachel Berry. Ex-coach of power team Vocal Adrenaline, and had a short fling with main character Will Schuester. She eventually takes charge of a new glee club at McKinley High. She is portrayed by Idina Menzel and has a complex personality.
Shelby Corcoran is one of my favourite characters on Glee because she is portrayed very well.
