Dermot Weld's Utterly Heaven is the only supplementary entry for Friday's Coronation Stakes at Royal Ascot at York.
Connections of the Irish raider have stumped up the £18,000 fee to add the daughter of Danehill to the field after she finished fourth in the Irish 1000 Guineas last time.
She could again clash with Ralph Beckett's Penkenna Princess, who finished second, as well as the David Wachman-trained third Luas Line and Barry Hills' fifth-placed Maids Causeway.
Wachman also has Damson in the race as she bids to make up for her disappointing ninth place in the Irish Guineas.
Aidan O'Brien's English 1000 Guineas winner Virginia Waters has also been confirmed for the race after finishing a well-beaten fourth in the Vodafone Oaks last week.
The John Gosden-trained Karen's Caper was fourth at Newmarket and she is set to reoppose, as is the fifth, David Elsworth's Cape Columbine.
O'Brien also has the Oaks ninth Mona Lisa in the contest, while Michael Stoute's one-time Guineas fancy Discuss could finally get the chance to show her Group One credentials after being slow to come to hand in the spring.
The Danzig filly missed the Classic but she romped away with a Bath maiden on her seasonal bow last month and could step up in class here.
A 13-strong entry is completed by the French raider Chantilly Beauty, Mick Channon's Love Thirty and Mark Usher's Royal Alchemist.
