Demi took to the outdoor stage at Niagara Falls for an Entertainment Tonight TV special and rang in 2014 while wrapped in dozens of layers.
The former US X Factor judge bundled up in leggings, tights, a hat and thermals before topping off her outfit with a giant coat.
Sharing a funny picture on Twitter, Demi told her fans: "Thick tights + leggings + thick jeans + thick socks + uggs + tank top + long sleeve thermal + long sleeve turtleneck + coat + scarf + hat + gloves = #ETcanadaNYE."
She then cheekily joked: "Don't let all these warm layers fool you..... Underneath it all, I still got my birthday suit on... #ETcanadaNYE."
Demi also posted a snap of herself while standing by a grand piano. She added: "Two hours and two coats later..... Haha ❄️⛄️ #ETcanadaNYE."
Last month, Demi quit her role as a judge US X Factor as she wants to focus on her music career.
But first, the star is looking forward to taking some time out to chill: "Taking the month off.... Kind of... What am I gonna do?!!!?????!??"
