Fallen For You showed style and speed in equal measure to win the Coronation Stakes at Royal Ascot for the red-hot John Gosden operation.
William Buick brought the 12-1 shot through with a swooping challenge in the straight to run out a three-and-a-quarter-length winner over stalemate Starscope.
Irish History finished third, another two and a quarter lengths in arrears.
Buick and Gosden had combined earlier in the day to take the Albany Stakes with the deeply exciting Newfangled and struck again soon after the Coronation with Gatewood in the Wolferton Handicap.
Gosden said of Fallen For You: "She trained beautifully, worked well last Sunday morning, and we were ready for a big run.
"They went hard up front, there's a strong headwind and she was just sat there.
"She is classy, this is not a fluke."
Fallen For You made a winning reappearance on the all-weather at Kempton before finishing down the field in a Lingfield Group Three.
With 1000 Guineas heroine Homecoming Queen (9-4 favourite) setting a strong pace, Buick was keen to bide his time.
It proved a wise move as the pacesetters soon faltered.
The trailblazing tactics that were so effective for Homecoming Queen at Newmarket did not pay off in the Irish 1,000 Guineas and she once again faded quickly.
Irish Guineas winner Samitar fared best of the two Mick Channon-trained runners in fourth.
Buick said: "The fast pace suited her. Things have conspired against her in the past but today everything went perfect.
"She finished off really well and won easily. Like John said, this is not a fluke.
"The turn of foot was impressive against the best of her generation."
Chris Richardson, managing director for Starscope's owners, Cheveley Park Stud, said: "We're thrilled she's bounced back to her best.
"We drew a line under her Newbury run as she got upset in the parade.
"What she wants is a strong-run mile as I don't think she stays further.
"We'll see where John goes with his other fillies as she's ground dependent."
Simon Crisford, Godolphin's racing manager, said of third-placed Art History: "We're obviously delighted she's Group One-placed.
"She was a bit unlucky last time at Sandown and she's bred in the blue so it's great."
Mick Channon said of Samitar and the sixth-placed Laugh Out Loud: "We've no excuses.
"I'm pleased enough with Samitar but she was beaten fair and square.
"She's got lot of options and is in the Falmouth.
"Laugh Out Loud has been on the go a while and will have a break."
Homecoming Queen beat only two home, and her rider Joseph O'Brien said: "She just didn't fire."
Newfangled, meanwhile, was quoted at around 8-1 for next year's 1000 Guineas after her Albany display, and is set to appear next at York's Ebor meeting in August.
Gosden said: "We'll just go quietly now - Lowther, Cheveley Park, that sort of route - and then have a little holiday.
"Today you'd say she isn't a miler, but at home you'd say she could do any trip.
"It's my job to settle her down."
