Taylor Swift wasn't too pleased to see her ex, Harry Styles on stage at the MTV VMAs on Sunday night.

She was caught saying "Shut the f*** up" to best friend Selena Gomez as Harry and the rest of the One Direction band were thanking their fans for being awesome, just before they went on to announce Selena Gomez as the winner of the Best Pop Video.

Taylor and Harry split up in January after dating for only a few months, but Taylor is clearly still bitter about something.
