Kenny Chesney wears Chiefs jersey at Arrowhead Stadium concert

In shape country music star Kenny Chesney played Arrowhead Stadium on Saturday and he wore a Kansas City Chiefs jersey to show his support of the local team.

Don't worry ladies, Chesney or "The Ches" as he likes to be called, showed off his famous biceps by repping a basketball version of the Chiefs jersey, leaving plenty of room to let his "ceps" breathe.

No word if Riley Cooper was in attendance.
