The judge treated Hannah to some festive fun and games, as they headed to Hyde Park's Winter Wonderland in London, to enjoy some fairground rides.
Nicole and Hannah were joined by fellow judge Gary Barlow and his last remaining group in the competition, Rough Copy.
Nicole, 35, looked ready to attack as she sped around the course and geared her bumper car towards Hannah!
The 'Boomerang' singer wrapped up warm in a black leather jacket, black jeans and boots. She added a bit of bling to her outfit with an embellished grey beanie hat.
Hannah, who also looked cosy in a black fur jacket, grey headband and black leggings, looked like she was having a whale of a time as she got strapped in to one of the rides.
Take That frontman Gary looked like a pro as he completed the rides and daring roller coaster at ease. We didn't know Gary was such a thrill seeker!
In one photo, Gary, 42, is strapped in on a ride along with the boys, but not all of them looked like they were prepared for take off.
While Joey James and Sterling Ramsey appeared to laugh while gripping onto the handlebars, Kazeem Ajobe looked to be a little scared!
The night of fun was well deserved for Hannah and Rough Copy, who took a break from their gruelling rehearsals before this weekend's live show kicks off.
