Pop acts Jason Derulo and Flo Rida took to the Cheyenne Frontier Days stage Friday and kicked out the jams. Flo Rida's flight was delayed so the show started late, but the crowd was pumped anyway. Odds are neither performer has had this many cowboy hats in the audience at one time.

Although Derulo is known for his hit song "Cheyenne," this is the first time the multi-platinum artist has played Cheyenne Frontier Days. Derulo has had over 3 billion youtube views.
