Elton John

Elton John spoke with BBC Radio this week and told them that he will be performing at Prince Williams’ Wedding in some type of capacity. He told the station that he will “probably” perform, but then quickly joked “I’ll probably be outside busking.”

Okay so his response to BBC Radio wasn’t a resounding yes, but given that he performed at Princess Diana’s funeral and that he’s a long time friend of the crown, there’s a good chance he’ll sing something at the ceremony.

In the meantime Kate and William are busy planning their wedding, with official invitations for the April 29 ceremony expected to go out soon.

So will Sir Elton John perform. A spokeswoman tells PEOPLE:

“It is all speculation” and “Nothing has been determined. We are still in discussions. They are only now sitting down and starting to think about things.”

Our guess is that we won’t know much until the wedding date draws closer, after all the British Royal Family are famously known for their extreme privacy during personal matters.
