The Rocket Man singer, who is currently promoting his new animated movie Gnomeo & Juliet, was asked if he’ll be making any appearances on the US talent show, which recently kicked off its 10th season.
He told MTV News: 'I don't know if you'll see me on this season. But you won't see me judging, obviously! But I don't know if I'm going to be on it.
'They've always been very, very generous to the AIDS Foundation. I'm very, very grateful. They've been helpful to us. I don't know if I'm going to be on or not. I can't answer that question.'
