Billy Joel's ex-wife Elizabeth Weber is opening up about their marriage and what really led to her leaving her first husband, Jon Small, for the famed singer. "I never thought of Bill as the homewrecker," Weber exclusively told Us Weekly on Friday, August 8, adding that she needed to "tread carefully" because "Jon and I didn't have a great romance." Weber first met Joel when she was married to his best friend and bandmate, Small.
