Justin Bieber to promote New Zealand children's hospital album

Justin Bieber is set to front an advertising campaign for a charity album in support of a children's hospital in New Zealand.

The Baby hitmaker will be the face of the promotional ads for the Starship Christmas Album 2012, which boasts contributed songs from artists including Lady Gaga, Sir Elton John, New Zealand classical singer Hayley Westenra and Bieber himself.

The record will raise funds for the Starship Children's Hospital in Auckland.

Starship Foundation CEO Brad Clark says, "Starship is our national children's hospital and every day its extraordinarily talented staff do extraordinary things to look after our precious children when they need it most.

"The proceeds from this album will help support the amazing work they do for patients and their families. We're very grateful to the extraordinary lineup of artists who have generously contributed their music - they've already made this Christmas very special for Starship."

The singer and his girlfriend Selena Gomez visited sick kids at the hospital in July (12).
