Hayden Panettiere’s mom discloses heartbreaking ultimatum in their final phone call before actress’ death

Hayden Panettiere's mom is detailing the heartbreaking ultimatum that led to their estrangement months before the actress' death.

In an interview with "Good Morning America," which aired Monday, Lesley Vogel said she and the late actress had become estranged in the months before Panettiere's death after Vogel gave her daughter an ultimatum over her daughter's relationship with on-again, off-again boyfriend Brian Hickerson.

About a year ago, Vogel traveled to California to stay with Panettiere and help her end her relationship with Hickerson — a decision the "Nashville" star made on her own, Vogel claimed.

"She knew she had to get him out of her life." Vogel said things began to change after about six weeks, when she noticed her daughter slowly pulling away.

It was then that she returned home to Florida.

"I could not believe that she had gone that far back, that he had been successful in reeling her back in with all of the things he had done to her." Vogel said that, on the advice of her therapist, she told Panettiere that she could no longer speak with her as long as Hickerson remained part of her life.

The decision marked the beginning of their estrangement — something Vogel believed would only be temporary.

"Of course, I thought it was going to be a pocket of time.

I did not by any stretch of the imagination think that this was going to happen to Hayden." "I don’t know why, I just didn’t," she added.

"Maybe I didn’t want to." Panettiere was found dead inside a Greenville, South Carolina residence on Aug.
