It was a busy weekend for Calvin Harris!

The world famous recording artist, who's collaborated with Rihanna for their hit "We Found Love", played at the Firefly music festival on Friday night for a packed house.

And right after his performance at the Dover, DE festival, the Scottish singer and deejay jetted to Las Vegas for Electric Daisy Carnival, an EDM fest he played at twice on Saturday.

Calvin played poolside at Wet Republic on Saturday before spinning at Hakkasan nightclub that evening, where he has a residency. Although his rumored girlfriend Rita Ora joined him at Hakkasan back in May, she was nowhere to be seen this weekend.

Back at Firefly, the Red Hot Chili Peppers put a crowd-pleasing show for the 60,000 concertgoers and Tom Petty played for a full house on Saturday night which included Adrian Grenier.

The Lumineers were schedule to perform Sunday, but cancelled due to a bandmember's illness. Ben Harper took their spot instead, and Foster the People closed out Sunday's set.
