Play video content Taylor Swift is celebrating buying back her original recordings the best way she knows how … by singing her heart out to one of her biggest hits! In a clip shared Friday evening by Swift's close friend and longtime collaborator Jack Antonoff, the two are seen jamming out in a kitchen to "Getaway Car" — soaking up the moment after she sealed the deal on her masters. Swift clutches onto her cat Meredith as she lip syncs to the line "Put the money in a bag and I stole the keys" … before passionately shouting, "That was the last time you ever saw me."

The tune is from Swift's 2017 album "Reputation" … and Antonoff captioned the video, "Rep forever guilt free listening!" Swifties are eating up the now-viral video … which racked up millions of views in no time. As you know, Taylor shared a detailed letter on Friday, revealing she now owns her entire music catalog after finalizing a deal to buy it back from Shamrock Capital.

This comes after years of battling to reclaim her original masters — which were first sold to Scooter Braun in 2019, then later sold to Shamrock Capital.
