The Roger Charlton-trained daughter of Frankel impressed in her first two starts in June and July last year, before finishing third in the Lowther Stakes at York and second in the Rockfel Stakes at Newmarket.
Harry Charlton, assistant to his father, said: "She won't have a prep run. She will go straight to the Guineas. She went to Kempton last week and worked well.
"You invariably have a hard race in a trial if you win it or finish second or third. Physically she has done very well. She has grown and put on a lot of weight. Mentally she is good.
"I get the the impression having watched the John Gosden horse win at Chelmsford City the other day they (Frankel offspring) are still doing the business and wanting to win."
