Taylor Swift and Prince William Sing Along to "Livin' On A Prayer"
Sadly, it was the toned-down acoustic version Bon Jovi played (so as not to wake Prince George?), so while it was mad seeing Prince William and Swift join in, there were a lot of awkward interludes while Bon Jovi strummed his guitar.
No matter, because Swift played some of her hits as well, including "Trouble" and "Love Story."
"This has reference to palaces, princes and princesses and it is very strange that I end up playing it in a palace," Swift said to the audience, according to Daily Mail.
"It is my first time playing at Kensington Palace or any other palace for that matter.
"I have to thank you, Prince William, for having me. It’s amazing. To call attention to this age group especially, teens and young adults."
The night benefited Centrepoint, a charity focused on eradicating youth homelessness. Princess Diana worked with the organization in the years before her death, and William has taken part in their "sleep out," where ambassadors and volunteers spend a night out on the streets of London with the homeless.
