Ged Fulton, 29, will become a granddad in November when the 18-year-old girlfriend of his 15-year-old son, Sean, gives birth, the Sun reported Sunday.

Fulton, a resident of Greenock, was all of 14 when he became a dad and expects his youthful son to be "a good father."

"It hasn't sunk in yet. I'm getting teased by my mates -- but I've got no plans for a pipe and slippers yet," Fulton told the British newspaper.
