Hayden Panettiere's final weeks have come under fresh scrutiny after friends reportedly raised concerns that the actress had become increasingly isolated from the people who cared about her, amid the return of her troubled on-and-off relationship with Brian Hickerson.
The Nashville star died aged 36 in South Carolina on 16 August, after authorities responded to reports that she had been found unresponsive. Her cause of death has not been officially confirmed, while police have said there were no signs of foul play.
