Michael Bolton is a grandpa! The Grammy award-winning singer’s daughter Taryn, 31, gave birth to a daughter earlier this week.
“A profound and indescribable joy has been delivered to my heart and to our entire family,” Bolton tells PEOPLE.
This is the first grandchild for Bolton, 56, who has three daughters from a previous marriage.
