Valerie Bertinelli has gained and regained shape before our eyes. On One Day at a Time, we watched her, as "Barbara Jean Cooper," develop from an awkward 15-year-old girl into a sexy young woman. More recently, we have shared her triumphs as she dropped pound after pound as the new Jennie Craig spokesperson. In Losing It, this popular veteran of numerous TV films entertainingly recaps her continuing fight against flab by placing it in the context of her often-troubled personal life, including the end of her 20-year marriage to rock star Eddie Van Halen. This memoir speaks candidly about the joy of motherhood and what it was like to be the wife of a music legend.
