Harris also seemed to confirm that the exes were on good terms, tweeting out a message that they shared "love and respect for each other." Swift retweeted it.
However, eagle-eyed fans noticed on Wednesday that something was UP. Harris deleted the breakup tweet and unfollowed Swift on Twitter.
He also, according to one Twitter user, tweeted, "it's about to go down," before deleting the tweet.
The ex-couple are also deleting pictures of each other on Instagram, according to fans.
ALSO, people are pointing to a video of Swift and Hiddleston getting pretttty friendly six weeks ago at the Met Gala.
In fact, Hiddleston talked about the "dance-off" a few days later on MTV.
"I sat next to her at dinner that night and she was very charming. She is amazing — I've seen a couple of her videos," he said.
