Sad news.

The talent manager and close friend of the American reality personality died in an all-terrain vehicle (ATV) accident on Wednesday morning (2 July).

The news has only started to be reported this morning, with reports claiming she collided with a moving vehicle while riding the ATV near Jenner's Malibu residence.

TMZ reported that the impact caused the ATV to leave the road and to fall into a more than 100 metre deep ravine.

She was pronounced dead at the scene.

The occupants of the other vehicle were unharmed.

It is unknown whether Jenner was present at the time of the crash.

Hutchins, who is also a transgender woman, first got in touch with the 'Keeping Up with the Kardashians' star ten years ago in 2015, following Jenner's public announcement about her gender transition.

She would later go on to appear on Jenner's reality series 'I Am Cait' while also managing many of Jenner's business affairs.

Since becoming friends, the pair have often appeared together at big events.

Like Jenner, Hutchins was a supporter of the Republican Party and publicly backed former US President Donald Trump.

Last year she posted a photo on social media beaming beside Trump at his Mar-a-Lago estate, captioning it: "The energy, passion, and commitment for our movement to Save America has never been greater! We will never give up!"

The 29-year-old was also a devout Catholic and often posted about her faith online.

Jenner is yet to comment on her close friend's death.
