R&B singer Cee Lo Green has become a grandfather at the age of 35.
The Forget You hit-maker'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 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.
