Billy Joel, 68, and wife Alexis Roderick are expecting a baby

Billy Joel will soon have three Uptown Girls to worry about!

The iconic artist, 68, unexpectedly shared with the Belfast Telegraph that he and his wife are expecting their second child. He wed Alexis Roderick, 35, in July 2015, and she gave birth to their daughter Della Rose the following month.

Roderick is due next month, which means that Joel will soon have two very little tots at home. "This one is good," he said of Della. "She sleeps through the night. I hope the next one will."
