Taylor Swift was upset after missing a note during her Grammys performance.

Gomez, 23, comforted Swift with a hug and the singer later bounced back and was in feisty form as she hit out at Kanye West during her Grammys acceptance speech.
While picking up the gong for Album of the Year, Swift noted that she is the only woman to have ever won the award twice and urged young women to "focus on work" and ignore people who try to "or take credit for your accomplishments or your fame".
She said: "As the first woman to win Album of the Year at the Grammys twice, I want to say to all the young women out there, there are going to be people along the way who will try to undercut your success or take credit for your accomplishments or your fame.

"But if you just focus on the work and you don't let those people sidetrack you, someday, when you get where you are going, you will look around and you will know that it was you and the people who love you who put you there. And that will be the greatest feeling in the world. Thank you for this moment."
Swift's comments came after West claimed in his new song Famous that he was responsible for making her famous, after memorably crashing her 2009 acceptance speech at the MTV VMAs.
