Allemand, who was taken off life support Wednesday after an apparent suicide attempt, was “an angel,” he tells PEOPLE.
“I am in complete shock and devastated to hear the news about Gia,” says Pavelka, who romanced Allemand, 29, on season 14 of The Bachelor. “She was one of the sweetest people I have ever known. And a very dear friend. My heart goes out to her family during this very difficult time. We have lost an angel today.”
The model and actress, who also appeared on two seasons of Bachelor Pad, was found in her New Orleans home on Monday by her boyfriend, NBA player Ryan Anderson of the Pelicans, her family says in a statement. He called 911 and Allemand was transported to the hospital in critical condition.
