He played a nearly two-hour set, surrounded by a few friends
The DJ returned to work Friday for the first time since splitting with Taylor Swift, his girlfriend of 15 months, and seemed to not miss a beat – literally – during his nearly two-hour set at Las Vegas’ Omnia, the same place where he rang in the new year with Swift in January.
“Las Vegas, how you feeling?” Harris, 32, asked from his booth, surrounded by a few friends, but no women. “I feel good.”
He commanded the room as he whipped through his late-night set, which started at 1:30 a.m. and included his own songs, including the hit “Feel So Close,” and remixes of other songs (but none of Swift’s tracks).
He later took the microphone to tell the crowd, “Friday night: If you’re feeling good, make some noise.”
After that, he spoke little, which is common during his sets.
Harris’ split from Swift, 26 – which was confirmed by multiple sources exclusively to PEOPLE – was not the result of any drama, according to one source.
“Things just don’t work out sometimes,” the source said. “No one cheated.”
But one Swift friend told PEOPLE that Harris was “intimidated” by her multi-platinum success, “which is why he would not attend any events where she was being honored, or any award shows unless he was nominated,” the friend said.
Meanwhile, a source close to the DJ told PEOPLE “that couldn’t be further from the truth. He has global success. Why would he be intimidated by anyone?”
Regardless, a Harris insider told PEOPLE he still “very much admires” Swift.
“She works incredibly hard for things that she believes in,” the Harris source said. “He always saw that as an amazing quality. They are still friendly.”
