this is what probably really happened. he didnt want to tour for awhile so he could slam the shit out of katy perry's pussy for ten months strait then when he got tired of her morning breath. Back on the road
his voice sounds lower. wonder if that's permanent or just a temporary result of whatever the fuck they injected into his neck.
its not permanent. if his been out for 10 months then his chest voice hasn't been in that place for awhile so the musculature is not stretched out as its used too but that part in his voice will be back. just takes a little time.
