Washington, Feb 8 : Zac Efron recently expressed his concerns for Demi Moore, who is presently undergoing emotional trauma.

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. (ANI)
