Lionel Richie is a proud new grandfather – though he's still getting used to his new status, the singer said in a statement Tuesday.

"While it may take me a moment to adjust to being called grand dad, I am extremely happy and proud of Nicole and Joel," Richie says, referring to the birth of his granddaughter.

"Harlow Winter Kate Madden, the newest and most beautiful addition to the Richie clan, is a lucky little girl," he added. "She was surrounded by a great deal of love at that hospital as she entered the world. Nicole and Joel are going to be wonderful parents."

Nicole Richie and Joel Madden welcomed their daughter on Friday.

Madden, 28, posted a message on his Web site Monday, saying that their daughter "looks so much like her mom its crazy," and expressing appreciation for all the well wishes they have received.
