'It Ends With Us' author Colleen Hoover shares cancer diagnosis in candid hospital post

Bestselling author Colleen Hoover is sharing her personal health battle.

"I wish I could blame my hair and facial expressions on @Texas.Oncology, but they've been great," Hoover wrote. "Hope you never need them, but highly recommend them." 

The author did not specify the type of cancer but has been quietly navigating the diagnosis for months.

Hoover's health update comes amid continued scrutiny surrounding the film adaptation of her blockbuster novel "It Ends With Us."

Lively also detailed allegations of intentional infliction of emotional distress and negligence against Baldoni and producer Jamey Heath in a complaint first filed with the California Civil Rights Department and later in federal court.

While she was present for only a few days of production, Hoover said she was "completely unaware that anything was happening" at the time.

As the controversy surrounding the film continues to grow, the bestselling author said she finds the situation both "unfortunate" and "disappointing," describing the fallout as overwhelming and damaging.

"It feels like a circus," Hoover said. "When there are real people involved, with real feelings and emotions. This actually truly has impacted some of the actors' careers in huge ways. And I just find it all around sad."
