Avril Lavigne has some fun on day two of filming with a saw blade electric guitar on the set of Rock N Roll in Palmdale, Los Angeles, CA, USA on July 26, 2013. The sexy blond rocker chased around what appeared to be a bear shark with a mad max style guitar with a saw blade on it. She laughed as she charged the man in costume and even fell to the ground as she slipped in the sand. Photo by GSI/ABACAPRESS.COM27/07/2013 - Los Angeles - Foto
