A winner on her racecourse debut at Salisbury, the filly was turned out just six days later for the Chesham Stakes at Royal Ascot and ran an excellent race to fill the runner-up spot behind Aidan O'Brien's 1000 Guineas favourite September.
She found another Ballydoyle inmate, Clemmie, too strong in the Duchess of Cambridge Stakes at Newmarket earlier this month and is set for another chance at Group-race level.
Nyaleti holds an entry in the Jockey Club of Turkey Silver Flash Stakes at Leopardstown on Thursday, but is set to remain on home soil.
Johnston said: "She is an intended runner in the Princess Margaret at Ascot on Saturday.
"She's in good form and Ryan Moore rides. That's the plan."
