The 35-year-old singer showed off her adventurous side on Tuesday (7 January) after posting a photo of herself on Twitter.
Nicole, who looked cosy in a padded coat and brown beanie hat, was seen clutching a round-shaped lip balm in the snap.
The brunette beauty, who styled her hair into pigtails, also proved that she's a complete natural on the snow after telling fans that she had been snowboarding for the entire day!
We can just imagine Nicole zooming down the trails, taking in the scenery and saying 'sch-mazing' all at the same time!
Captioning the photo, Nicole said: "Snowboarding all day, now night sledding... @eos break for the brutal winds and cold #megazone."
Nicole's photo follows a week of rising speculation that she has reunited with ex-boyfriend Lewis Hamilton.
Formula One racing ace Lewis, who celebrated his 29th birthday yesterday, is thought to have rekindled his romance with Nicole over the festive season.
Nicole and Lewis, who split in July, have been on several skiing trips together in the past, and appeared to have been on a winter break in the same location after posting individual photos on snowmobiles.
Although posing in separate photos, the pair also spent New Year's Eve partying with Alicia Keys and her husband Swizz Beatz.
