The 32-year-old actor, who plays high school senior Teddy, enjoyed the spotlight in Season 3 when his character came out the closet. Donovan will appear in about five episodes as a guest-star when the show returns this fall.

As previously announced, Lori Loughlin and Ryan Eggold have both exited the series, paving the way for West Bev's brightest youngsters to head to college — or get knocked up, like Naomi (AnnaLynne McCord) did. Showrunner Rebecca Sinclair also left the series, replaced by Life Unexpected's Patti Carr and Lara Olsen.
