Audrina Patridge, who came to fame on The Hills for six seasons from 2006 to 2010, recently announced the death of her 15-year-old niece, Sadie Loza. The adolescent girl was born in 2008 to Casey Loza, Audrina’s sister, and Aaron Hershman, whom Casey previously dated.

Audrina paid tribute to her late niece on Instagram on Tuesday. “I know it’s not goodbye forever, but it is the hardest to say goodbye for now. We shall miss you and treasure every time we shared with you. Hey Say, rest in peace!! We will adore you forever and ever!” she said, adding that it “hurts to even write this.”

Brody Jenner, Rachel Bilson, Paris Hilton, Ashley Greene Khoury, Kaitlyn Bristowe, Selma Blair, Nicky Hilton, Christa Allen, Kandee Johnson, Becca Tilley, and many others expressed their love, prayers, and sympathies for Audrina and her family in the comments area.

Casey Loza also used Instagram to convey the devastating news of her daughter’s death; like Audrina Patridge, she acknowledged how tough it was to write the post, calling it the “hardest thing I have ever had to do.” It’s understandable that she was having difficulty finding the perfect words to say.

“Sadie likes to remind me that the first law of thermodynamics is also known as the law of conservation of energy,” Casey wrote in the caption. “Transformation is preferable to death.” Her story will save many lives. Her memories will live on forever. “You dazzling starseed, rest in peace.”

Kyle Loza, Sadie’s stepfather, also posted a tribute on Wednesday. “I’ll keep your memory with me till I see you again. I can’t get you out of my mind. I’ll never stop loving you, and I’d do anything to laugh with you again. “You were my first Love,” he said in the caption, signing it ‘Dad.’

Kyle married Casey in 2009, the year after Sadie was born. Kyle is a freestyle motocross racer and musician. One year later, the couple welcomed their first child, a soon-to-be 13-year-old son named Draven, who was born in April 2010. They also have a 4-year-old son named Vallon, whom they welcomed in October of 2018.

Did you know Audrina Patridge has her own daughter? Kirra Max, her six-year-old daughter, was born on June 24, 2016, just a few months before she married motorbike and BMX rider Cory Bohan. They began dating in 2008 and dated for eight years before marriage.

Regrettably, the marriage was short-lived. Patridge filed for divorce and a restraining order against Bohan about a year after they married, citing abuse and violence. Patridge’s divorce was finalized in December 2018, giving her some piece of mind about her and her daughter’s safety.

Patridge hasn’t worked on many major projects since her stint on The Hills. She competed on Dancing With the Stars Season 11 and made it to the sixth week before being eliminated; she finished in seventh place with her dance partner, Tony Dovolani.

Our thoughts go out to Audrina Patridge and her family in their time of grief. Sadie died just a week after celebrating her 15th birthday. The cause of death has not been revealed, but it is a tragedy in any case. It’s just another reason to keep folks you care about as near as possible.
