Last year's Lowther Stakes winner had her stamina limitations exposed in the fillies' Classic at Newmarket where she weakened at the business end to finish ninth to Winter.
"We gave it a go. She didn't stay. She'll go back to sprinting now," told At The Races.
"I've even put her in the King's Stand. She is that quick. She's in the three-year-old sprint (Commonwealth Cup) as well. We'll see, but we're very comfortable and very happy with her."
One of Fahey's stable stars who will not be going to Royal Ascot is Don’t Touch, who has yet to be seen this season.
The five-year-old, who was a close fifth to The Tin Man in the British Champions Sprint at the Berkshire track in October, has had his reappearance put on hold following a minor setback.
"He was due to have a run this week, but I'm afraid he got a touch of gravel that's just slowed him down but he's in great form," said Fahey.
"The owners are not keen to go to Royal Ascot.
"We are thinking of stepping him up in trip this year. On pedigree he could stay further and it might make life a little easier for him and give him a few more options.
"He'll be ready to rock soon. You find with the better horses there are less races to run them in. If he doesn't stay seven you can count in one hand the number of races there are for him, so we'll see."
