Tamara Ecclestone has broken up with her boyfriend after a video emerged of him in a seedy sex romp, it emerged today.
The daughter of Formula 1 tycoon Bernie Ecclestone dumped Omar Khyami - whom she had previously spoken of marrying - when she found out about the sleazy video.
Before yesterday she had no idea about the romp, which is believed to have been filmed at a London address while Mr Khyami was taking part in a friend's stag night.

After finding out, the 28-year-old heiress is said to have packed his belongings and sent them to his parents' house before changing the locks on the West London home they share.
Last night, Miss Ecclestone was in tears as she spoke of her heartbreak at finding out about the film.
She told The Sun: 'I have spoken to Omar and he has admitted that it's true. It's over now.'
Tamara added that she had spoken with her father Bernie and mother Slavica who, sources said, were both extremely upset to have learned of their daughter's heartbreak.

'I feel sick about what has gone on,' Miss Ecclestone added. 'This will draw a line under it.'
The split came after Miss Ecclestone and Mr Khyami attended the London premiere of new Batman movie The Dark Knight Rises together on Wednesday night.
While Miss Ecclestone posed up for photographers at the event in a black and gold beaded dress, Mr Khyami stood in the background - happy to let his girlfriend take centre stage.
Last night, Tamara referenced a difficult few days, writing on her Twitter page: 'Crap day people never fail to disappoint but I really hope what comes around goes around.'

Miss Ecclestone is now said to be with her father and mother, who are offering her comfort during a difficult time. They had earlier discussed the video's emergence at Mr Ecclestone's Knightsbridge office, the Sun reported.
Miss Ecclestone also spoke on the phone with her younger sister Petra, 22, with whom she is very close.
It was then that she called Mr Khyami - and dumped him immediately.

Mr Kyami told the Sun that Miss Ecclestone was being 'hotheaded'. He said that the video had been filmed before the were together and claimed it only emerged because he was being blackmailed.
However, he admitted he had not made a report to the police about the alleged blackmail.
Just weeks ago, Miss Ecclestone and Mr Khyami were enjoying a sun-soaked holiday in Croatia, where she tweeted pictures of them together on the island of Hvar.
Miss Ecclestone has in the past been vocal about her desire to marry Mr Khyami, who she has been with for more than two years.
There were even rumours last month that he may have proposed to her after she stepped out brandishing a huge diamond ring as she held an early birthday party.
