Tamara Ecclestone is heiress to a £2.7 billion fortune

Tamara Ecclestone has dumped her boyfriend Omar Khyami after seeing saucy footage of him.

The heiress - whose father is Formula 1 tycoon Bernie Ecclestone - threw Omar out of her home and changed the locks when she found out about the tape.

'He's admitted it - it's over. I feel sick,' says Tamara, 28.

'I have spoken to Omar and he has admitted that it's true. It's over now. I have spoken to my dad and I have spoken to my family.'

The video of Omar, 38, was reportedly shot at a stag party for one of his friends.

But he denies that he cheated on Tamara.

'This wasn't a relationship. This was my friend's stag. We were all messed up and drunk. I didn't even know what the hell it was,' Omar tells The Sun.

'Tamara is being hot-headed. I dispute everything. This was before I was with Tamara.'
