Surely there's a word missing in the question... a "fake" what?
Fake Person ... no I think he's a person

Fake Singer .... no I think he's singing live

Fake Star ... well the public will decide that one
I can only assume that this fake/phoney thing relates to his image/behaviour ??? If so I still don't get it. This is showbiz people, it's full of people with public images different to how they really are.
But don't let that get in the way of a good bandwagon.... btw Rylan must be really pi**ed at all the coverage Chris is getting.
