Frankie Dettori steered Star Of Seville to a famous victory in the Prix de Diane Longines at Chantilly just nine days after she was well beaten in the Investec Oaks.
John Gosden’s filly suffered interference when seemingly running out of stamina in the closing stages of the Epsom Classic, but a drop back in trip saw her return to her best.
Derby hero Dettori always had Star Of Seville (PMU 171-10, industry SP 16-1) close to the lead set by Clarmina, a pacemaker for the favourite Queen's Jewel.
While the field bunched up turning in, Dettori was able to get first run on the Musidora winner as he took her to the front.
She maintained the gallop to see off Physiocrate (PMU 41-5, ISP 10-1), with Little Nightingale (138-10, ISP 12-1) third.
Queen's Jewel was never able to land a blow.
The other British raider, Mick Channon's Malabar, briefly looked as though she might get involved but could not get close at the business end.
Gosden said: "Frankie and I walked the track this morning and came up with a plan of what to do.
"He has ridden her beautifully and I said after we walked and planned it, 'if this works you are a genius'.
"She will have a break and then she could run the Nassau Stakes and the Prix de l'Opera.
"I don't think she is an Arc filly, I think she is better over the mile and a quarter.
"She is a great filly, who is very strong mentally."
On the decision to run so soon after Epsom, Gosden said: "She went very, very slowly (at Epsom) and ran for a furlong and a half up the hill and got knocked over. It was a very expensive piece of work, but she came out of it almost angry she didn't have a race.
"I left her in the first few days [at Chantilly] and I called [owner] Lady Bamford and said 'this filly is in great form, she is back to her racing weight, please can I run her as she didn't have a run at Epsom'.
"I said 'I know it isn't the normal way to prepare a horse, but please can I run her' and she was very sporting and said yes."
