Taylor Swift resurfaces and sings ex Calvin Harris's song she co-wrote

Taylor Swift made a triumphant return to the stage last night to prove her career is NOT over.

The Shake It Off hitmaker , who has had a rough few months with boyfriend and Kardashian drama, was in high spirits as she performed her only full concert of 2016, during the Formula 1 United States Grand Prix at Circuit of The Americas in Austin, Texas.

According to E! News, she also sang Calvin Harris's hit, This Is What You Came For, in its entirety - after her rep confirmed she'd co-written the song under the pen name Nils Sjoberg before the pair split.

Dressed in a thigh-skimming black sparkling playsuit, she flaunted her incredible pins and belted out her best tracks for the crowd.

She matched her outfit with a pair of fierce black shiny boots and wore her blonde hair down with a full fringe on show.
