Strauss, who appeared on season 8 of the series, entered hospice on November 22, according to reports. Strauss had reportedly chose to stop her chemotherapy treatments near the end of October and was moved to hospice mid-November.
Her addiction left her with rotting teeth and her body covered in sores.
After receiving treatment for her addiction and getting clean, the model said she was "the happiest I've ever been in my entire life". "I need another one of those miracles that I got back in 2013" ― a reference to her overcoming substance abuse that year.
It added: "The chemotherapy has been brutal for her, and it has taken its toll on her".More news: North Korea, United States: Leaders to Meet Early Next Year, Trump Says

In a statement to TMZ, her family said: "The one blessing was that we were able to show her how loved she was before she passed".
Strauss took to Instagram to celebrate the anniversary of her sobriety on August 17.
After cameras showed up to Jael's house, she agreed to visit the show - but before being brought onto the stage, she fled the set, leading to Dr Phil speaking to her in the Paramount lot. She has just begun chemo, but we do no know how things will play out. She has created "gofundmes" for literally dozens of her friends, and it is now time for us to pay her back.
According to reports, Strauss had been unconscious in the days leading up to her death and her family were no longer allowing visitors. It's really awesome. It's a huge miracle to still be breathing after what I was up to and I'm so grateful. "Service work feels better than the greatest high, Sobriety makes you weirder not normal and I'd be dead if it weren't for all the love and forgiveness I've been showered with by my friends and family".
