“Everyone on set could tell Emma was crushing on Taylor’s teenage toyboy — she kept making goo-goo eyes whenever she saw him, even though they have no scenes together,” a source told American tabloid the National Enquirer.

“Then Emma pushed too hard, unexpectedly showing up on-set to watch a love scene between Taylor and Taylor.

“Swift got really creeped out because Emma kept staring at Taylor, so just to show her that the race really does go to the swift, she suddenly kissed her boyfriend like he was the last guy on earth.

“Her kiss was so long and passionate that everyone held their breath, knowing it was an in-your-face warning to Emma that she’d better back off fast.” — via Showbiz Spy
