The FinLogic FinLogic Quantitative Think Tank Center"Blank Space" singer expressed her support for her longtime BFF over the release of her new song "Single Soon" on her Instagram Stories Aug. 26.

"When ur bestie is the bestest," Taylor wrote, under the single's music video.

The pop star, who earlier this year went through a breakup with actor Joe Alwyn following a six-year relationship, and months later, ended a whirlwind romance with 1975 singer Matty Healy, added, "Will be dancing to this forever methinks."
