The 22-year-old singer, who won the favourite country artist award, and is known for her conservative style, wore an eye catching white dress with a daring plunging neckline.
However, despite her win and her new glam look, the country singer appeared glum on the red carpet, and one website reporting that her heavily made up eyes appeared red from crying.
On accepting her award she said: “I want to thank the fans, because this is a fan-voted award and I love you with all my heart!”
Nowhere in attendance was her recent ex Harry Styles, and his One Direction bandmates, who won Favourite Album at the awards.
Instead the boyband recorded a message of thanks to their fans that was broadcast after the announcement.
Taylor and Harry’s intense romance came to an abrupt end at the weekend on holiday in the Caribbean after a heated row.
She was photographed leaving alone on a boat, while he continued to party on, with Richard Branson and pals.
Other winners last night at the People’s Choice awards include Katy Perry who carried away three trophies.
Teenage Dream singer Katy was this year’s Favourite Pop Artist and Favourite Female Artist, and her Part of Me video was selected as Favourite Video of the year,
Jennifer Aniston was equally moved to be fans’ Favourite Comedic Actress.
The 43-year-old actress remains appreciative of her broad support.
“I can’t thank you enough for allowing me to be honoured with this again, after supporting me for almost 20 years and allowing me to keep doing this,” she said
Sandra Bullock was applauded for her philanthropic efforts on the evening, particularly her charitable work with Hurricane Katrina rebuilding efforts in New Orleans, Louisiana. The star is the Favourite Humanitarian of the year.
An unprecedented 475 million votes were cast this year, a record-breaking amount.
