Businessman to pay his ex-fiancee one million euros he promised her before finding out she was a high class prostitute. Love was blind, now it has eyes.

A wealthy London businessman has been ordered to pay one million euros to his ex-fiancee that he promised her before learning she was a prostitute.

A Monaco court heard that Dutch-born Robertus Thielen, 52, proposed to the Russian call girl two years ago. 

He handed her a cheque worth £862,000 as 'unconditional financial security'. It was to be cashed after their marriage.

But he discovered earlier this year that the 30-year-old, who was named only as Diana, was a high-class escort. 

The court heard she was selling sex in London, Moscow and the French Riviera - and that the wealthy property tycoon had even been paying for her flights as she jetted across Europe servicing her clients.

Mr Thielen swiftly called off the engagement and demanded that she return gifts and jewellery including a £60,000 diamond engagement ring.

His ex-lover refused, but when the one million euros cheque was bounced by Thielen's Monaco bank, the call girl took him to court to demand her money.

Smart girl, dumb man. This is why divorce is so high. You don't know someone but because she is fine and great in bed, you must marry her. Where did you think she learnt does wicked skills in bed room. Church?
