Billy Joel is a dad again.
The 66-year-old "Piano Man" singer and his wife, Alexis Roderick, 34, welcomed daughter Della Rose Joel on Wednesday in New York, People confirms.
The couple's pregnancy news surfaced in April, just a few months before they tied the knot at a surprise Fourth of July ceremony.
New York Gov. Andrew Cuomo presided over their wedding at Joel's Long Island estate. Alexa Ray, Joel's daughter with his second wife, model Christie Brinkley, was among the people in attendance.
Joel and Roderick have been dating since 2009. Roderick has worked for Morgan Stanley as a risk assessment officer. In 2010, she told the New York Daily News that she met the "Piano Man" at a Long Island restaurant.
Joel has been married three times before -- to Elizabeth Weber Small, Christie Brinkley and Katie Lee. It's Roderick's first marriage.
