R&B singer Cee Lo Green has become a grandfather at the age of 35.
The Forget You hitmaker's 20-year-old step-daughter Sierra recently gave birth to a baby boy and the star is thrilled with the new addition to his family.
He tells U.S. talk show host Chelsea Handler, "I'm a grandfather. I'm 35. She had a son so I have a grandson."
Sierra is Green's step-daughter from his marriage to Christina Johnson.
It's not the only good news Green is celebrating - the singer was nominated for five Grammy Awards on Wednesday (01Dec10).
