The couple are spending time together in a luxury ski resort
The pair – who ended things in June because of work commitments – posted sweet matching Instagram photos of themselves at a ski resort in Aspen, Colorado yesterday.
Both snaps showed the stars wearing protective gear while posing next to snowmobiles, with a stunning orange sunset clear in the background.
‘What better way to kick off 2014 in God’s Country! Praying and snow mobiling! #Everything! #Glorious!’ Nicole, 35, captioned her snap.
Lewis, 28, wrote: ‘Great way to enter the year….snowmobiling with Gods view. Truly am blessed to have a great family with me. #OneLove.’
X Factor judge Nicole is believed to have flown to Aspen last weekend, where Lewis and his family have been holidaying since before Christmas.
But it seems her decision to jet to the romantic destination may have been a last minute one.
‘It came as news to everyone really, up until the end of The X Factor their relationship was still off,’ a source tells The Sun.
‘It’s not as if they were secretly together all that time, so it’s a new development.’
