Singer Melissa Etheridge said Wednesday that her 21-year-old son Beckett Cypher died as a result of his drug addiction.

Today I joined the hundreds of thousands of families who have lost loved ones to opioid addiction, the two-time Grammy winner wrote on Instagram. My son Beckett, who was just 21, struggled to overcome his addiction and finally succumbed to it today.

My heart is broken, added the Come To My Window singer, who shared Beckett with ex-partner Julie Cypher.

We struggled with what else we could have done to save him and in the end we know he is out of the pain now, she continued.
