Demi Lovato performed at Entertainment Tonight Canada's New Year's Eve at Niagara Falls celebration on Tuesday, December 31. The 21-year-old singer performed some of her hits at the event.

Braving the cold weather in a black leather jacket, a pair of leather pants and a black scarf, she sang "Neon Lights", "Heart Attack" and "Nightingale", new singles off her latest album, "Demi". She also belted out "Skyscraper", a track from her 2011 album "Unbroken".

Hours before the performance, Lovato posted Instagram photos of herself in a long sleeve turtleneck, coat, hat and gloves. "Don't let all these warm layers fool you..... Underneath it all, I still got my birthday suit on...," she captioned the pic.

In an interview with ET later that day, Lovato expressed her excitement to be able to perform at Niagara Falls. "I've never performed in front of Niagara Falls so it will be interesting," she said.

"I wanna look forward to life and what the next year has to offer other than forgetting the last part of my year," she added. "I think there's so much fun that people can have on New Year's Eve without getting crazy and hopefully some of my fans will come and do that with me."

This year, Lovato will embark on her "Neon Lights" tour with Fifth Harmony from "The X Factor (US)" and former contestants of U.K.'s "The X Factor" Little Mix and Cher Lloyd.
