The stunning songstress made her first public appearance on Wednesday (3 July) since the rumours of her break-up surfaced and managed to put on the best brave face we've ever seen, as she beamed for the cameras and entertained the Welsh X Factor fans.
Nicole, 35, looked as glamorous as ever for the auditions and even colour co-ordinated her outfit with the red carpet, as she stepped out in a vibrant red suit and a white cropped top that flaunted her toned torso.
She completed her outfit with a pair of black heels, a few gold chains and a slick of red lipstick, while keeping her long black hair down and straightened to perfection.
Formula One racing driver Lewis and Nicole were said to have called time on their five-year relationship earlier this week, after a source claimed that the couple were struggling to see each other in between their hectic work schedules.
If true, this wouldn't be the first time that the two stars have split due to work commitments, since they also briefly broke up in 2010 and again in 2011.
However, news of their third split has come as a bit of a surprise, as Lewis recently hinted that he was planning to pop the question to Nicole before their sixth anniversary.
The pair have yet to comment on whether they are still together, but Nicole seems to be coping well either way by putting her all into her X Factor judging role.
On Wednesday morning she tweeted a picture of the sunny weather in Cardiff and wrote: "The sun is shining down on us in Cardiff today, getting ready for @TheXFactor."
