Passenger X boarded the aircraft and proceeded to self-upgrade himself to a better seat.  When he was asked about this by another FA; he held his ground.  Apparently; out in the gate area; he was quite belligerent.  So; a member of the ground staff had to come on board and move him back to his assigned seat.  He said that he was fine.  After takeoff and constantly throughout the flight; I had to ask him to put his mask on.  It happened several times.  He was not happy that I kept asking him.  I guess he felt that he was exempt from the wearing of masks.
Flight Attendant reported a passenger was not compliant with face mask policy and also moved to a better seat without asking FAs.
