Billy Joel never slows down. We all know that he does a monthly show at Madison Square Garden in NYC! In between those shows, he tours around the country performing. And now we just found out that at age 68, he's about to be a dad again!!! His first daughter, Alexa Ray, from his marriage to Christie Brinkley is now 31 years old. He also has a two year old daughter with his current wife Alexis. And now we've found out that they're expecting again, and she's eight months along. So while we don't know if it's a boy or a girl, we do know that we'll find out soon enough! Congratulations to Billy and his wife!
