Natalia Borodina, 35, from Moscow, had taken her bikini off and was playing up to the camera, hauling her top half out of the car window while a friend was driving.
The shocking video sees the mother-of-one letting her upper body hang out of the window of the moving car, before she hits a lamp post.
The video was recorded on a highway near Punta Cana, in the Dominican Republic.
It was filmed by Ms Borodina’s friend Ivanna Boirachuk, 32, who is believed to have been driving the car.
Russian media reports that Ms Borodina was rushed to hospital and died there of ‘serious injuries’.
‘The woman was having fun demonstrating her naked breasts while her companion drove the car,’ reported Moskovsky Komsomolets.
It is understood Ms Borodina’s child, a boy aged around eight, was on holiday with her in the Dominican Republic.
