Another day, another Glee retcon. This one comes from Idina Menzel, who appeared in a few episodes of the infamous show as Shelby Corcoran—Rachel Berry’s biological mother and one-time “Poker Face” duet partner. (We’re still wondering about that particular song choice, but hey, at least they sold it.)
From the outside, Ryan Murphy’s decision to cast Idina Menzel as a relation of Lea Michele’s is a no-brainer. They were—and still are—two of Broadway’s most famous belters, and there’s no denying the physical resemblance between the two. Their names even sound kinda similar! Again… no-brainer. Still, mother may have been a step too far; according to Menzel, at least.
