Aidan O'Brien's Moth has been supplemented for the Qipco 1000 Guineas at Newmarket on Sunday.
Beaten in both starts as a juvenile, the daughter of Galileo appeared much improved when running out an impressive winner of a Curragh maiden on her three-year-old debut at the Curragh in early April.
O'Brien revealed afterwards the first fillies' Classic of the season would be considered and she has now been added to the field at a cost of £30,000. The master of Ballydoyle also has Magical Dream and Snow Queen in the mix.
Sir Henry Cecil's hugely impressive Nell Gwyn scorer Hot Snap is the ante-post favourite and features among 18 confirmations.
Charlie Hills' star filly Just The Judge remains in the hunt, as does the Mikel Delzangles-trained French challenger What A Name.
Richard Hannon could saddle Fred Darling winner Maureen and Nell Gwyn runner-up Sky Lantern, but one significant absentee is William Haggas' Rosdhu Queen.
Unbeaten as a juvenile but beaten into fourth when seemingly failing to stay seven furlongs in the Fred Darling, the three-year-old is set to revert to sprint distances.
Haggas said: "We think she'll be better over shorter and we've decided to give up on the Guineas. She worked at the weekend and is in great form.
"I think that race (Fred Darling) has done a lot of good, but she needs to be better than that at a mile and I can't see it. She has a lot of speed, she is good at going fast, so let's use that as a major weapon."
Leading Irish handler Dermot Weld has Big Break and Rasmeyaa in the field, while other contenders include Roz, Ollie Olga and Diaminda.
