Carly Rae Jepsen’s warm New Year’s Eve secret

North Stars

Carly Rae Jepsen had a unique (and secret) way of kissing off the cold in New York on New Year's Eve.

The Canadian songstress looked perfectly cozy as she performed "Call Me Maybe" and "This Kiss" in the frosty winter weather of New York on Monday night for Dick Clark's New Year's Rockin' Eve with Ryan Seacret. This despite the fact that she only wore a thin black sheer top with her midriff exposed.

As it turns out, Jepsen's festive poppy red Sachin + Babi maxi skirt, which was full tulle and touched the floor, was the secret to her success.

"Had a blast performing in Times Square!" she tweeted Monday night. "Nobody knew i had long johns under my skirt...till now;) #RockinNewYearsEve."

The 27-year-old B.C. native performed alongside stars Taylor Swift, PSY of "Gangnam Style" fame and perhaps her favourite performer of all, MC Hammer.

"Lookie here it's MC Hammer time!!" she tweeted with a photo of her with the "U Can't Touch This" singer. "Best New Year ever! @Happpynewyear"
