Boyfriend Eoin Treanor, her escort at the 2010 festival, was with Adrienne when she fell ill and was beside her when she died.
Her parents arrived in Ireland on Thursday morning while many of her fellow Roses maintained a vigil at her bedside.
Rose of Tralee Festival manager Oliver Hurley said: “It was with great sadness that we received the news of the untimely death of Adrienne.
“We extend our deepest sympathy to Adrienne’s family, her boyfriend Eoin and to her fellow Roses.”

An Irish dancer since she was four, Adrienne had danced with Gaelic Storm and Frank Patterson and held a masters degree in social work from the University of Texas.
