A full-sister to 2012 Oaks winner Was made a world record figure for a yearling filly sold at auction of 5million guineas at Tattersalls Sales October Sale in Newmarket on Wednesday.
The daughter of Galileo by Alluring Park was sold by Lodge Park Stud to Mandore International on behalf of Sheikh Joaan's Al Shaqab Racing.
Her fee also broke the all-time record for a horse sold at European auction.
A full-brother to Secret Gesture had set a new European record for a yearling sold at auction on Tuesday when John Magnier and his Coolmore partners paid 3.6m guineas.
Mandore International's Nicolas de Watrigant said the filly will be trained in France by Andre Fabre.
He said: "She is a magnificent specimen.
"We bought her sister last year and we think she could be special.
"We didn't want to miss this one - let's hope she is the next Treve.
"We didn't expect to pay that sort of price, but Al Shaqab Racing is keen to invest.
"She goes into training with Monsieur Fabre."
