Billy Joel, 68, expecting second baby with wife Alexis Roderick, 35

Billy Joel is about the become a father for the third time.

During an interview with the Belfast Telegraph, the 68-year-old revealed that he and his wife Alexis Roderick, 35, are expecting a baby.

"We are due next month," the 'Piano Man' singer told the publication.

The story noted that Alexis was “heavily pregnant" at the time the interview was conducted – which was in September – so she'll likely be giving birth very soon.

Billy and Alexis, who married in July 2015 after six years of dating, are also parents to 2-year-old daughter Della Rose.

"This one is pretty good," Billy said of his toddler. "She sleeps through the night. I hope the next one will."

Billy is also a dad to Alexa Ray Joel, 31, with his supermodel ex-wife Christie Brinkley who he was married to from 1985 to 1994.

And he's been enjoying fatherhood the second time around, too.

"I hang out with [Della Rose] and watch her little wheels spin," he said. "And she’s a hoot. She’s a funny kid. She loves to laugh. I like to make her laugh."

Decades after their divorce, Billy and Christie still get on well.

"I think that [being friends with your ex-wives] is a good thing," he told the outlet.

That bond also extends to his first wife Elizabeth Weber, who he was with from 1972 to 1982, and Katie Lee, whom he was married to from 2004 to 2010.

Congratulations, Billy and Alexis!
