The 18-year-old, Aleexandra Khefren, 18, working with German escort agency Cinderella Escorts, had initially set the price at £850,000.
Khefren’s parents had threatened her saying if she went ahead with selling herself, they would disown her.
This resulted in a storm of publicity and a flood of high bids.
Cinderella Escorts is reportedly taking 20% of the proceeds – with bidding set to close in February.
The company said, “The date takes place in Germany. The buyer can choose a hotel here, where Aleexandra will visit him for a night.”
