Addressing Max, Jessica added, “Mommy LOVES you! You are my guidin’ light forever foralways. I am strong because of you my sweet daughter.”

Jessica has also booked another big performance: She’ll headline the 5th annual Women Who Rock benefit concert, taking place Sept. 5 in Pittsburgh, PA. The event is a benefit for the Magee-Womens Research Institute, the country’s biggest research institute dedicated to women’s health research.
