Prince William recently opened up about a time Taylor Swift convinced him to do karaoke!
The event happened in 2013 at a charity event at Buckingham Palace.
After he watched Jon Bon Jovi perform, he thought the night was just about over.
He revealed that he had actually been sitting next to Taylor Swift at the time.
She took his arm and told her to come up on stage with her.
William said he "got up like a puppy and went."
However, he forgot the lyrics of the song halfway through!
He was just glad that the event was for charity and people were having a good time.
He said that sometimes when you're out of your comfort zone, you just have to roll with it!
