According to "Fox News,' Prince William, 42, can be seen on recording letting loose at the event and dancing from his seats.

This is not the first time that Swift, 34, has rocked with royalty. Back in 2013, she and Bon Jovi called Prince William on stage to sing along with their rendition of "Living On A Prayer." The song is reportedly one of the royal's favorite karaoke jams.

Recalling the karaoke moment, Travis shared on the podcast, "Tay got him out of his shell and sure enough he went up there and they ripped it, and they said he had a blast and I'm just like, 'I don't know if any other prince is doing that.' You know what I mean? In terms of royalty... It seems like they like to sit back and the show is the show, but he was cool enough to be a part of it. But that just shows you how personable he is."
