Well, It looks like Taylor Swift's feisty comments go beyond just the lyrics of her songs.
As her Ex Harry Styles took the stage with his band One Direction, Taylor Swift was spotted mouthing 'Shut the F--K up.'
Why you ask? We are not too sure but we are just going to assume that it was not a clean breakup.
Later in the night when the "Red" singer won the VMA for Best Female Video for "I Knew You Were Trouble" shout out to her Ex again saying "Who i wrote this song about because you know exactly who you are and now i have one of these."
It was been previously reported that the song was written about the One Directioner.
