Walking hand in hand, the adorable duo was spotted visiting the Starship Children's Hospital in Auckland, N.Z.
The pop star is no stranger, though, to the Starship Foundation. When he launched his Believe Charity Drive to encourage fans to contribute to charities around the world, the Biebs selected Starship, which raises money for the hospital.
"Do something nice for someone else today," he tweeted shortly before Thursday's visit. "U know your truth...do it for the right reasons."
