The electronic deejay will be spinning at Caesar Palace's Omnia Nightclub in Las Vegas, where he currently holds a residency.
The DJ usually wraps his set around 2:30 a.m. and according to a source, "he doesn't really hang out in Vegas or get involved in the community at all. He literally just parachutes in and out of town every Friday."
Harris, 32, was forced to cancel several of his appearances at the nightclub following his May 20 car accident and brief hospitalization while he took some time to recover from his injuries.
Ironically, that's the same day Swift, 26, and Harris were last photographed together – outside an airport sharing a hug and a kiss.
Multiple sources confirmed the pair's split exclusively to PEOPLE on Wednesday, with an insider explaining, "There was no drama. Things just don't work out sometimes. No one cheated."
The pair broke their silence on Twitter on Thursday when Harris wrote, "The only truth here is that a relationship came to an end & what remains is a huge amount of love and respect." Swift retweeted the message.
