“Piano Man” singer Billy Joel and his 33-year-old wife Alexis introduced their newborn daughter, Della Rose, in a photo he shared with his fans at his Philadelphia concert Thursday.
“Billy is thrilled to become a dad again,” a source told PEOPLE in April.
Joel, 66, and Alexis were among several celebrity couples who tied the knot on the 4th of July. Alexis is Joel’s 4th wife.
Joel will likely miss major milestones in his newborn daughter’s life as he ages in place. He will be nearly 90 by the time she graduates college.
Joel has a 29-year-old daughter, Alexa Ray Joel, by his ex-wife, former supermodel Christie Brinkley.
“Celebrating the arrival of my precious little sister this week,” Alexa wrote on Instagram.
