The trio belted out the Bon Jovi classic at the end of a gala event at the London palace in support of the homeless charity Centrepoint, of which 31-year-old William is patron.
Bon Jovi began the performance alone with his guitar, but the second-in-line to the British throne and Grammy-winning pop diva Swift came on stage to join him, to huge cheers from the crowd.
Wearing full black-tie, the prince made a decent attempt at the choruses but spent the more obscure verses nodding along with his hands awkwardly clasped in front of his dinner jacket.

He high-fived 23-year-old Swift, who rocked out onstage in a sequinned cream dress.
"Nights like this happen once in a lifetime," Bon Jovi told the crowd.
"But the chance to effect change can last a lifetime. Each one of you tonight have that chance to effect change."
William took a night off from looking after his baby son Prince George, who was born to his wife Kate in July, to attend the event and present Bon Jovi with an award for his own work combatting poverty and homelessness.
Bon Jovi founded his Soul Foundation in the United States in 2006. The charity aims to help Americans out of poverty by giving them access to food, training and affordable housing.
William has been patron since 2005 of Centrepoint, which works with young homeless people in London and northeast England.
