Caitlyn Jenner said she is going through “tough times” following the July 2 death of her longtime friend and manager, Sophia Hutchins, who was killed when her speeding all-terrain vehicle (ATV) lost control on a winding road near their Malibu home and plummeted into a ravine.

Hutchins was driving the vehicle near Jenner’s $3.5 million Malibu condo when she collided with the bumper of a moving car on Wednesday morning.
