Audrina Patridge, who rose to prominence in The Hills for six seasons between 2006 and 2010, recently revealed that her 15-year-old niece, Sadie Loza, passed away.

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. “I know it’s not goodbye forever, but it is the hardest to say goodbye for now. We will miss you and treasure every moment we had with you. Rest in peace!! We will love you forever and ever!” she wrote, adding that it “hurts even to 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 condolences for Audrina and her family in the comments section.

Casey Loza also used Instagram to share the heartbreaking news of her daughter’s death; like Audrina Patridge, she expressed how difficult it was to write the caption, calling it the “hardest thing I have ever had to do.” She had difficulty finding the right words to say, which is understandable.

“Sadie liked to remind me that the first law of thermodynamics, 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 memory will live on forever. You brilliant Starseed, rest in peace.”

Kyle Loza, Sadie’s stepfather, also posted a tribute. “I’ll keep your memory with me until 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 wrote in the caption, signing it ‘Dad.’

Kyle married Casey in 2009, the year after Sadie was born. Kyle is a freestyle motocross rider and musician.

One year later, the couple welcomed their first child, a soon-to-be 13-year-old son named Draven, born in April 2010. They also have a 4-year-old son named Vallon, whom they welcomed in October 2018.

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

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

Patridge hasn’t worked on many significant projects since her time 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 hearts go out to Audrina Patridge and her family in their 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 another reason to keep those you care about as close as possible.

It’s almost over for Audrina Patridge and her estranged husband Corey Bohan.

The former couple has reached a settlement in their pending divorce.

Patridge and Bohan jointly filed court documents on Oct. 2 stating that they have reached an agreement and plan to submit a “stipulation for judgment” with the court soon.

According to the court documents filed to the Superior Court of California, County of Orange, and obtained by The Blast, both Patridge and Bohan signed the document.

The terms of the agreement have not yet been revealed.

The former couple filed for divorce in September 2017 after 10 months of marriage. Patridge, 32, and Bohan, 36, welcomed daughter Kirra Max in June 2016 before tying the knot in Hawaii in November. They had been dating on and off since 2008 before their engagement in November 2015.

The filing comes just two days before Bohan filed court documents to legally prevent their toddler daughter from appearing on the upcoming reboot of The Hills.

On Oct. 4, Bohan requested that his and Patridge’s 2-year-old daughter not be filmed for the upcoming MTV reality series, in which Patridge has agreed to star in.

Bohan has requested “neither party to allow the minor child to be filed [sic] or to appear in any reality television production without the express, written consent of the other parent” and “any prior consent for the minor child to appear on ‘The Hills’ reboot to be revoked and proof of revocation to be provided,” according to the court documents.

According to Bohan’s declaration, he believes that Kirra potentially appearing on the reality show is not in her “best interest.”

Bohan stated that he does “not believe it is in Kirra’s best interest to appear on reality TV as the effects of being in the public spotlight could be extremely damaging to such a young child and could result in potentially dangerous interactions with fans and/or paparazzi” and alleged “that any consent that Audrina has given to allow Kirra to appear on ‘The Hills’ reflects poor judgment.”

In addition to requesting joint legal and physical custody, Bohan stated in the declaration that he is also asking for “a specific order restraining Audrina from allowing Kirra to appear on any reality television program including, without limitation, ‘The Hills’ without my prior written consent.”

“I further request that Audrina be restrained from allowing any further filming of Kirra to take place and for her to revoke any prior consent she may have given for Kirra to appear in any episode of ‘The Hills,’ ” it continues.

Additionally, Bohan requested a “2/2/3 or 2/5 parenting schedule,” and that Patridge pays his attorney’s fees and costs, which are estimated at $50,000.

The pair was ordered to attend an appointment for child custody mediation or child custody recommending counseling on Dec. 20, 2018.
