Lionel Richie performing live in concert at 'Sydney Entertainment Centre'. Sydney, Australia - 07.12.07

The Hello singer released a statement on Tuesday (15Jan08), saying he's "extremely happy and proud" of the new mum and her partner, Joel Madden, who welcomed baby Harlow Winter Kate Madden into the world last week (11Jan08).

But he admits, "It may take me a moment to adjust to being called grandad."

He added, "Harlow Winter Kate Madden, the newest and most beautiful addition to the Richie clan, is a lucky little girl.

"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."
