Prince William nervously joins Taylor Swift and and Jon Bon Jovi on stage at a Kensington Palace Charity event for 'Livin' on a Prayer' last month! The prince seems to get more comfortable as they get into the song a bit more, even high fiving Taylor at the end! BUT NOW, word is that the Queen is not too happy! She doesn't think a future king should be behaving like that and scolded William for his recent actions. William thinks he can be royal and real at the same time. We think the Queen needs to lighten up! CLICK HERE to see photos from the unexpected moment.
