Watch Taylor Swift, Bon Jovi, Prince William Sing "Livin' on a Prayer"

FUSE TV - Watch Taylor Swift, Bon Jovi, Prince William Sing "Livin' on a Prayer"

Talk about a royal affair! 

For a charity event at Kensington Palace, Bon Jovi invited Taylor Swift and Prince William onstage for perhaps the most star-studded singalong of "Livin' on a Prayer" ever. Watch above.

The rock legend strums his classic No. 1 hit on an acoustic guitar before the country-pop princess and real-life prince step in and sing along on its infectious chorus. The trio put a mellow, folky spin on the traditional rock version of "Livin' on a Prayer" that fans have come to know and love. Still, it's pretty awesome.

In other "Livin' on a Prayer" news, the iconic track returned to the Billboard Hot 100 last week thanks to a viral video of a Boston Celtics fan dancing and lip-syncing to the song. That video racked up over 11 million views worldwide, launching the song to No. 25  on the singles chart. Watch below.

Will views of Swift, Bon Jovi and Prince William's version of "Livin' on a Prayer" trump that of the Celtic fan video?
