The 'Don't Hold Your Breath' singer ' who worked with Simon on the UK version of 'The X Factor' as a guest judge and is hotly tipped for a role on the US form of the show ' enjoys a great relationship with the music mogul and particularly enjoys watching him have his make-up put on.
She said: ' have a great relationship with him, we have a blast. I have so much fun teasing Simon we hang out.
'He has what I call a 'powder face'. Whenever the make-up artist puts a light coat of powder over his face he leans back, closes his eyes and relaxes like he is meditating. He's very peaceful.'
The 32-year-old beauty is currently dating British Formula 1 driver Lewis Hamilton, and when the pair enjoy some time together they love eating and 'get crazy' having a games evening.
She told the Daily Mirror newspaper: ' don't have much down time but when I do I love to cook for him. I make this dish my family in Hawaii make, oyster chicken ' it's been in the family for years.
't's chicken, lots of vegetables and rice, so it's really healthy. If I wanna get crazy I'll have game night. We play 'Cranium', 'Taboo' or cards. I can kick a*s but Lewis is pretty good at cards - although he's pretty good at everything.'
