According to a source, the baby is a girl and will be Billy's second child. He has a daughter, singer-songwriter Alexa Ray Joel, who's now 29 years old with his former wife Sports Illustrated Swimsuit model, Christie Brinkley. The source added that Billy is extremely excited to become a dad once again.

Another source close to the couple claimed that the couple plan to call the newest addition to their family, "Madison." 

Billy and Alexis, who is a former financial advisor at the Morgan Stanley and an equestrian, started dating Billy after they met at a restaurant. The two were reportedly friends before they started dating. They have been together for six years already. 

An insider revealed that there are several family photos that show Alexis and her growing belly, though she's been keeping a low profile-avoiding leaving the house too often and wearing loose dresses to keep the pregnancy under wraps.

His representative explained that the extremely thrilled coupled decided to keep further details about Alexis' pregnancy private until their daughter makes her official debut.

Although the couple are not engaged, a report by the National Enquirer last year claimed that Billy had gifted her a diamond ring.

Before he met Alexis, who will turn 34 next month, Billy was previously married to Elizabeth Weber from 1973 to 1982, Christie Brinkley from 1985 to 1994 and to Katie Lee from 2004 to 2010.

Billy is currently completing his residency at Madison Square Garden, New York and will start his next show on May 28.
