Taylor Swift appeared to vent against former boyfriend Harry Styles not once, but twice at the MTV Video Music Awards on Sunday night (Aug. 25).

Swift, 23, took home the award for Best Female Video for ‘I Knew You Were Trouble.’ She seemed to take a shot at Styles after thanking her supporters. Later in the evening, Styles and his One Direction band mates took to the stage to present an award. The couple dated for a few months before breaking up in January. Swift, who was also captured on camera dancing to the ‘NSYNC reunion, told reporters on the red carpet that she is working on songs for a new album.
