VIDEO: Bon Jovi, Taylor Swift, Prince William sing ‘Livin’ on a Prayer'

Prince William invited Bon Jovi and Taylor Swift to perform at the Winter Whites Gala, a charity-fundraiser event for homeless youth, on Tuesday in London.

The highlight of the evening came when Bon Jovi took out his acoustic guitar to perform “Livin on a Prayer” – but he wasn’t alone. Taylor and William joined in on the tune, lending some unique background vocals to the classic rock melody.

Tuesday’s event was benefiting one of Prince William’s most beloved charities, Centrepoint, which focuses on helping and supporting homeless young people.
