London, Nov 6 A video of a blonde flashing her boobs at a car of cheering Brit teenagers before her vehicle smashes into the rear of a lorry has received more than 2 million hits after it was posted over the internet a month ago.

However, doubts have been expressed about the genuineness of the footage.

The clip shows a bunch a teenaged boys flirting with girls who are driving alongside.

The boys then shout asking them to roll down their windows.

"What you doing? What's your name, what's your number?" the Sun quoted a boy, as yelling in a British accent.

And soon the same boy screams: "Get your t*ts out!"

The giggling blonde in the front seat takes no time to oblige the guy - she pulls down her top to reveal her bra.

Her action prompts one of the grinning guys to say: "Straight on YouTube!"

The boys cheer the girl more and ask her to repeat the feat as she turns around to laugh with her friend.

Only seconds later the girls crush their speeding car into the back of a lorry.

The guys are all panicked now and can be heard shouting: "Call 999!"

The Internet user who has posted the video has kept mum about its authenticity. (ANI)
