Lionel Richie is excited about having more grandchildren, but being called grandpa has him singing a different tune.

The singer told Entertainment Tonight on Monday that hes thrilled his youngest daughter, Sofia Richie Grainge , is expecting a baby girl with her husband, music executive Elliot Grainge. But he has some thoughts about what the child will call him.

Im Pop-pop, he said. We dont get the grandpa, yeah, thats a little deep. Pop-pop is where were going.

Richie is already a grandfather to his daughter Nicole Richies kids. The former reality TV star shares two children with her husband, singer Joel Madden.

The Hello singer shared similar sentiments with People magazine back in 2008 after the birth of Nicole Richie and Maddens daughter, Harlow Madden, who is now 16.

While it may take me a moment to adjust to being called granddad, I am extremely happy and proud of Nicole and Joel, he said at the time.
