“Today I joined the hundreds of thousands of families who have lost loved ones to opioid addiction,” the 58-year-old singer wrote in the post. “My son Beckett, who was just 21, struggled to overcome his addiction and finally succumbed to it today. He will be missed by those who loved him, his family and friends. My heart is broken.”
