Maybe Taylor Swift isn't so innocent after all.
The Internet exploded last night during the 2013 MTV Video Music Awards when it appeared Taylor mouthed the words "Shut the f**k up" to BFF Selena Gomez while her ex Harry Styles was on stage.
One Direction took to the mic to present a VMA -- and Swift's reaction has gone viral.
But, did she really drop an F-bomb? Watch the video above.
A lot have speculated she's actually saying "Sorry for my arm" to Gomez, who's sitting right next to her.
