A touch of Saturday Night Live is coming to Glee.
Molly Shannon will guest star this May on the musical comedy, playing a role that sounds almost too delicious to be true.
Originally reported by EW.com and then backed up by E! News, Shannon will portray Brenda Castle. She'll be a nemesis for Sue and:
"[A] busty 45-year old new astronomy teacher and badminton coach at McKinley high-school who is both an alcoholic and a pill-popper," said an insider.
Ignoring the atrocity that was Kath & Kim, Shannon has appeared on episodes of Pushing Daisies and 30 Rock.
Glee (fianlly!) returns to Fox on April 13.
