Efron, who has been a friend of Moore's daughter Rumer Willis since a long time, also said that despite going through a tough phase, the 49-year-old is handling her time of crisis in a fine manner.

"Yeah, she's doing OK. She's doing fine," the Us magazine quoted him as telling E! News. "It's tough, but I think she's all right.

"Me and Rumer have been friends for a long time. I know Demi is going through some personal stuff right now. I just wish her well. I hope she's doing okay," he added.

The 'High School Musical' hunk spent time with the troubled 'Margin Call' star, who was partying hard and hanging with her daughter's pals in the wake of her Ashton Kutcher split before her hospitalization and top-secret rehab stay.
