Barely a week after breaking up with Thor star Tom Hiddleston, Taylor Swift uploaded an Instagram video featuring her and "squad" member Martha Hunt singing along to Calvin Harris' song "This Is What You Came For" in the background.

The two were seated together in the front row of "TOMMYXGIGI" New York Fashion Week while Gigi Hadid was strutting on the runway.

Swift, 26, posted this caption to her recent most talked about Instagram video, "So Proud of You Gigi!!!! That's show was INSANE. Congrats to Gi, Tommy, and all the girls who just owned the runway!!

The popular video gained more than 6.5 million views with a significant digital "thumbs-up" from for ex-boyfriend Harris (real name Adam Wiles). The music producer's thumbs up caused a barrage of up to 19,000 comments.

Swift and Harris' breakup fiasco gained more attention after it emerged that "This is What You Came For" was written and sung by the "Bad Blood" singer, Glamour reports. According to E! News, Swift and Harris' relationship just fizzled out. The two didn't figure in any sort of public drama prior to their split. "They were just not very compatible in different areas in their relationship," a source close to the ex-couple said.

Another source said, "Taylor and Adam [Harris] had no big blowout fight, but the romance was just not there anymore for them. Adam is the one that ended it. It was all done in a very mature fashion. Taylor is pretty upset but they are still in communication." With the recent Instagram video thumbs-up, people are now wondering whether Swift and Harris are going back together or if the two are throwing shade against one. Perhaps they exchanged DMs after the post? Only the two of them could tell.
