Taylor Swift -- Sheds a Tear, Pisses on Kanye

Taylor Swift wiped a tear away after apparently blowing a note in the Grammys show opener, "Out of the Woods."

Once seated the cameras caught Taylor complaining to Selena Gomez, "I missed that note."

She changed gears later in the show when she clearly dissed Kanye West, whose lyric "I made that bitch famous" pissed her off. She told the crowd "People will take credit for your success ... Don't let them knock you down."
