Billy Joel is poised to become a father for the third time at the age of 68.

Joel's representative confirmed to CNN that the singer's fourth wife, Alexis, 35, is due to give birth to their second child next month.

The couple are already the parents of 2-year-old Della Rose, about whom Joel told The Belfast Telegraph: "She sleeps through the night. I hope the next one will."

Joel also has a 31-year-old daughter, Alexa Ray Joel, with his second wife, model Christie Brinkley.
