Jennifer Maas TV Business Writer Valerie Bertinelli‘s departure from “Kids Baking Championship” is not a cut-and-dry case of Food Network firing the “One Day at a Time” alum from her role as co-host and judge of the show. Rather, it’s the aftermath of the Warner Bros. Discovery-owned channel deciding not to renew Bertinelli’s larger exclusive deal with the network when it ended in 2022, sources tell Variety. Bertinelli signed a multi-series deal with Food Network in 2018, which expired in 2021.
