Seventh Heaven led home stable companion Found to provide Aidan O'Brien with a one-two in the Darley Yorkshire Oaks.
Last year's Breeders' Cup Turf heroine Found was the marginal favourite at 2-1, bidding to get back on the winning trail after a hat-trick of runner-up finishes at Group One level against the boys.
Seventh Heaven was sent off at 100-30 in the hands of Colm O'Donoghue as she aimed to prove last month's surprise victory in the Irish Oaks was no fluke.
O'Brien fielded four runners in all and it was the least fancied of the quartet Pretty Perfect who took the field along for much of the mile-and-a-half journey.
As she began to falter halfway up the home straight, the Sir Michael Stoute-trained Queen's Trust moved smoothly towards the front, but the Ballydoyle big guns were waiting in the wings.
Seventh Heaven showed the best turn of foot to grab the lead and galloped all the way to the line to score by two and three-quarter lengths.
Found had to make do with second spot once again, with Queen's Trust a long way clear of the rest in third.
