This was my reaction as well:
I literally face-palmed. I can hardly believe he would do this.
As far as all of this "Ruining his legacy" garbage goes - the guy has traveled the earth this year and is currently in the middle of USA tour giving his fans an opportunity to meet him, talk with him, ask him questions, take pics and sign anything they bring up to him (including a toy baby... yeah check his facebook)... I would say that is solidifying his legacy
He can do all of those things while keeping his clothes on.
