Brad Paisley and wife Kimberly Williams-Paisley have revealed the name of their newborn son. Weighing in at 9 pounds, 10 ounces, Jasper Warren Paisley was born last week, almost two weeks overdue. The country star dad shared the baby's name with fans on his website late Monday afternoon.

A rep for the couple says the baby's middle name, Warren, is after Paisley's grandfather, who gave him his first guitar and encouraged him to pursue a music career. Jasper Warren joins older brother William Huckleberry -- Huck for short -- who is named after Mark Twain's character, Huck Finn.
