Bertinelli will portray Lovato's mother on the scripted comedy series, which follows a group of friends who are a part of a food issues group.
The group supports each other as they search for love, success and the perfect item to eat.
Bertinelli's character Lisa owns a resturant and likes to point out that she is best friends with her daughter Teddy (Lovato). Lisa is described as warm, loving, self-critical and an emotional mess.
Co-stars include Anna Akana, Alex Brightman, Ashley D. Kelley, Jay Klaitz and Rory O'Malley.
Bertinelli hosts Valerie's Home Cooking and Kids Baking Championship on Food Network, and is known for starring in One Day at a Time, Touched by an Angel and Hot in Cleveland.
Hot in Cleveland creator Suzanne Martin is writing and executive producing Hungry. Lovato is also executive producing with their manager Scooter Braun, Sean Hayes, Todd Milliner, James Shin and Scott Manson.
Lovato announced in May that they identify as non-binary and changed their pronouns to they/them.
