The DJ and producer tweeted, "The only truth here is that a relationship came to an end & what remains is a huge amount of love and respect" after news broke recently that he and Swift were done.
Swift, who was with Harris for 15 months, retweeted him.
There has been much speculation about what happened with the pop power couple.
In the May issue of Vogue, Swift talked about her relationship with Harris, whose given name is Adam Wiles.
"I'm in a magical relationship right now," she told the publication. "And of course I want it to be ours, and low-key. ... (T)his is the one thing that's been mine about my personal life."
