Zac Efron 'Rumer Willis Is Coping Well With Moore's Health Crisis'

Demi Moore's eldest daughter Rumer Willis is coping well as she supports her mother through her health crisis, according to pal Zac Efron.

The Ghost actress, who split from husband Ashton Kutcher in November (11), was hospitalised after suffering convulsions on 23 January (12).

She was treated for "stress" and "exhaustion" and briefly checked in to a treatment facility.

Rumer, whose father is action man Bruce Willis, has been at her mum's side throughout her personal struggle and Efron has assured fans the 23 year old is handling the situation well.

He tells Eonline.com, "Yeah, she's doing OK. She's doing fine. It's tough, but I think she's all right".
