Borodina can be seen in the video playfully climbing out of the car window. Music is playing in the background, and she yelps when she realizes just how far out of the moving vehicle she has climbed.
However, Borodina soon manoeuvres enough of her body back inside the car to begin her sexy display. She stares straight into the camera and seductively sticks her finger into her mouth before laughing.
It is not known whether or not Borodina was under the influence of drugs or alcohol at the time.
A few seconds later, Borodina unexpectedly hits a lamppost. On impact, she is immediately knocked out of the car, and erratic screaming can be heard.
The force of the hit was so strong that Borodina's blood ended up on the floor of Boirachuk's car in the passenger footwell.
According to Russian media, Borodina was rushed to hospital where she later died of "serious injuries".
"The woman was having fun demonstrating her naked breasts while her companion drove the car," Moskovsky Komsomolets reported.
This accident will have a devastating effect on Borodina's family, especially her child, and the role Boirachuk played in her friend's death will undoubtedly haunt her for the rest of her life.

Borodina, however, is not the only person to lose her life in such bizarre circumstances.
In 1983, an assistant manager at a club in San Fransisco died after accidentally activating a lift under the piano he was having sex on. This caused the piano to rise up towards the ceiling, leading to his untimely death.
We wish all the best to Borodina's family during this extremely difficult time.
