The singer goes on to reveal she was left in tears following the subsequent backlash.
"As I was performing, I could see these blank faces and no one said anything to me when I came off..." she adds. "And of course I then looked on Twitter and all I saw was a load of negative stuff and I got completely overwhelmed and was in tears. I know I've got to get tougher. Things aren't always how they look on the outside. I was a total mess."
The night was an emotional one for Goulding as she also lost out on the two prizes she was nominated for - Taylor Swift took the Best Song trophy for Bad Blood and Rihanna was named Best Female Artist.
Goulding has indulged her love of fashion and beauty by launching her own collection with MAC Cosmetics, putting together a range which includes mascara, false eyelashes, lipsticks, glosses, and eye and cheek compacts.
"I have so much make-up, but I still buy something new almost every day," she previously told InStyle magazine about her love of changing her look. "I always carry a Chanel blusher, Viktor & Rolf's Flowerbomb perfume and some eyelash curlers, which never fail to brighten up my eyes without me needing to add any mascara."
