But all was not always well in the bustling Eastwood family. Shortly before Christina's death, Kathryn and her half-sister Morgan appeared to be in a bitter feud. Although it is unclear what initially led to the hurt-feelings, following Morgan's wedding, Kathryn made a series of scathing posts slamming her on social media.

"I had to break up with my sister Morgan after her wedding because she’s so concerned with her reputation, she called me ‘insane’ online for the world to hear," she wrote at the time. "This has impacted my ability to have children and become a mother and I have to protect myself from further heartache from this image driven monster."

Kathryn also referred to Morgan as the "cruelest, most shallow superficial woman" that she's ever known."

"Zero compassion for others, obsessed with self-image and as cruel inside as she is beautiful without," she continued. "Her looks will fade like a flower and all that will be left is a heartless monster meet my evil stepsister."
