The 32-year-old DJ looked quite dapper when he arrived with some friends to the H. Wood Group's OUE Skyspace launch event at the U.S. Bank Tower in Los Angeles, California, on Thursday evening. An eyewitness at the party told ET that Harris took photos with just about any fan that asked and seemed quite friendly.
While Harris was busy mingling with his fans and hanging with the guys, the Keeping Up With the Kardashians stars were all about their Snapchat stories. Kardashian -- who has accused Swift of "playing the victim" over Kanye West's lyric about her in his song,"Famous" -- even snapped herself singing along to Harris and Rihanna's tune, "This Is What You Came For."
The summer hit caused some drama between the DJ and his ex earlier this week after Swift's team revealed that she had written the track's lyrics. Harris initially praised the 26-year-old singer for her musical skills, but then launched into a Twitter rant, even calling attention to her new relationship with Tom Hiddleston. "Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though," he wrote. "I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do."
