Even Food Network stars make mistakes in the kitchen, and in Valerie Bertinelli's case, her son, Wolfgang Van Halen, won't let her forget about it. The former Valerie's Home Cooking host, 65, exclusively told Us Weekly that her worst kitchen disaster is "anytime I burn something and my son's over, because then he never lets it go." The actress and "homegrown wiz in the kitchen" is partnering with Williams Sonoma and No Kid Hungry to end childhood hunger in America. Bertinelli opened up to Us about her support for No Kid Hungry, an organization she's worked with for a long time.
