Taylor Swift pulls sick face at Justin Bieber and Selena Gomez reunion kiss

Taylor Swift’s true feelings about Selena Gomez were caught on camera at the Billboard Music Awards when she was busted on camera pulling faces behind Justin Bieber’s girlfriend’s back.

Swift, who was the big winner on the night with 8 gongs, didn’t seem to realise the cameras were on her as she was subjected to a love fest backstage between Justin and Selena.

Taylor had walked into the backstage area chatting friendly with Selena before they bumped into Justin.

She was forced to wait as the lovers said hello to each other with a kiss.

Their affectionate moment seemed all too much for Taylor to stomach as she grimaced, pulling a sick face and sticking out her tongue.

Perhaps Taylor objected to playing second fiddle as her own friendship with Bieber goes way back.

Justin, 19, once famously helped punk Swift, 23, in a set up where a wedding boat set alight forcing her to scramble and call 999.
