It was revealed last week that the couple had split after five years together, and Lewis opened up about his feelings as he gave a subdued interview with Sky Sports, ahead of the German Grand Prix on Sunday.
Quizzed about his 'grumpy mood', he said: "You have different people who are able to keep in their emotions – I have a Finnish trainer, for example, who doesn’t show any emotion and they are always able to control it," he said.
"Me, I wear my heart on my sleeve and that gets me in trouble a lot of the time and I generally find it very, very hard to fight my emotions.
"I’m going through… I’m trying my hardest to be positive but I’m going through a really, really tough time at the moment with the loss of someone really, really special in my life. My world’s turned upside down, but I have a job…"
Asked if he was referring to Nicole, he confirmed: "Yup…but I have a job to motivate my team and if I come in with my head down and negative energy then that goes around to all my mechanics who work day and night, and I don’t ever want that. So I’m really trying to pull myself together and keep my head up but it’s so hard to do."

Following an emotional performance by a contestant who had written her own song about a breakup, Nicole is said to have commented: "It pulled on my heartstrings. It sucks doesn’t it? Really sucks."
Let's hope they can make it work.
