The actress, who split from husband Ashton Kutcher in November, was hospitalized after suffering convulsions on January 23. She was treated for "stress" and "exhaustion" and briefly checked in to a treatment facility.

Rumer, whose father is Bruce Willis, has been at her mom'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."
