Bruce Springsteen announces he's become a grandfather for the first time!

Bruce Springsteen can now add grandfather to his long list of accolades.

The legendary rocker's youngest son Sam and his partner recently welcomed a beautiful baby girl into the world, named Lily Harper.

Taking to social media to announce the birth of their first grandchild, the Boss's wife Patti Scialfa shared heartwarming photos of the new arrival.

The first photo, which is black-and-white, shows the new dad pushing a baby carriage with his arm around his soon-to-be wife.

The smiling couple appears to be walking along a road that's part of Springsteen's sprawling 127-acre farm in Colts Neck, New Jersey.

Scialfa also shared a gorgeous picture of the newborn wearing pink hospital mitts and a matching beanie cap.

Springsteen and his wife are also parents to son Evan, who works for SiriusXM Radio, and daughter Jessica, an equestrian who won a silver medal at last year's Olympics in showjumping.
