TVLine has learned exclusively that Hayes has booked a Season 4 guest-stint on the Fox comedy as a lust interest for Damon Wayans Jr.’s Coach.

The actress-writer will play Ruth, the slightly ditzy and trashy school nurse who’s having an fling with Coach and doesn’t appreciate the new “no fraternization” policy that Jess — the Vice Principal — must enforce.

Coincidentally, this is the same episode that marks the arrival of the hot new science teacher, played by Once Upon a Time‘s Julian Morris.

New Girl‘s fourth season kicks off Tuesday, Sept. 16 at 9/8c.
