You have to hand it to Jon Bon Jovi - he'll do anything to save one of his songs from being murdered.
The rock star was at a wedding in Miami, Florida recently, when the band decided to cover one of his band's most famous songs, 'Livin' on a Prayer'.
The 54-year-old Bon Jovi looks suitably mortified and uncomfortable as the band's singer, Lourdes Valentin - who said she knew he would be a guest and prepared the song especially for him - encourages/pressures him to join in.
He smiles/grimaces through the awkwardness before reluctantly taking the mic - perhaps to stop the singer getting any more of the words wrong.
