Taylor Swift is seen mouthing "Shut the F up" while ex-beau Harry Styles was presenting at the MTV Video Music Awards. It also connected the inspiration for her award winning video "I Knew You Were Trouble."

It seems like Taylor needs a dose of Beyonce's Sasha Fierce on her playlist as the bitterness factor seeps out.

As the camera timely focused on Taylor Swift alongside BFF Selena Gomez (totally on purpose), Taylor was seen with an agitated expression and one can clearly lip-read what she said.

After that, they kept on focusing on her the entire night, perhaps waiting for another F-Bomb. Maybe they should have invited all Taylor Swift's exes. The question is, would the Barclay's Center be big enough?

Taylor Swift's bitterness over failed relationships are notorious all over Hollywood. It is obviously a factor in her songwriting. One of her earliest hits, "Teardrops on My Guitar" portrayed a young, innocent heartbroken girl. It is highly unlikely that Taylor can still play the 'innocent' card now..but heartbroken is right up her alley.

Swift has had much success with heartbreak songs. Her biggest hits were about her break ups with John Mayer (so thinly veiled "Dear John"), Taylor Lautner ("Back To December") and Joe Jonas ("You're Not Sorry").

Swift received the Best Female Video award for "I Knew You Were Trouble" and seemed to hint at Styles in her acceptance speech: "I also want to thank the person who inspired this song, who knows exactly who he is, because now I got one of these!"
