She was found Monday night in her New Orleans home by her boyfriend, NBA player Ryan Anderson of the Pelicans, her family says in a statement.
Anderson called 911 and Allemand was transported to the hospital, where she was in critical condition on life support.
"Due to a critical loss of brain and organ function, life support was withdrawn" on Wednesday, the family statement says. "Ms. Allemand passed away peacefully with her mother, boyfriend, and other lifelong friends by her side. As a practicing Christian, Gia did receive the sacrament of last rites."
"Loved ones and fans will remember Gia Allemand as a caring woman who loved her family and was well-known for her compassion towards animals and mission to rescue homeless pets."
Allemand was one of Pavelka's top three contestants. She was also on two seasons of the spin-off series Bachelor Pad and modeled for Maxim.
Just a week before her death, Allemand seemed "in good spirits and appeared healthy" at an event on Aug. 5, according to a Tweet Tuesday by Ali Fedotowsky, who appeared alongside her on Pavelka's season.
Allemand – a New York native – had been working as a Pure Barre instructor in New Orleans, where she lived with Anderson.
"Gia you are my angel," season 14 winner Vienna Girardi Tweeted Wednesday. "You changed so many lives with your beautiful soul and will be missed and loved forever."
