T he model and singer told Elle France magazine's Olivia Lamberterie jokingly: 'I could do extreme gestures, like cut his throat or his ears when he's asleep for example.

'I think you should avoid to cheat if you can, it's too dangerous. It's a road to a break up.

'Also, fidelity, this is a sine qua non (essential) condition for a wedding, I guess. Why cheat and lie whereas you have the possibility to choose your life, get married or not, have kids or not.'
