Zac Efron 'wishes Demi Moore well'

Zac Efron has sent a message of healing to Demi Moore, the mother of his longtime friend Rumer Willis. The "High School Musical" star says that he "hopes Demi's doing OK" after being hospitalized on Jan. 23 for "substance abuse."

"Me and Rumer have been friends for a long time. I know Demi is going through her own personal stuff right now. I just wish her well. I hope she's doing OK," Efron told "Extra." He adds, "Rumer's doing great. I talked to her on the phone. It's got it ups and downs, but she's doing OK."

Efron's name has popped up multiple times in reports following Moore's hospitalization and subsequent announcement that she had "chosen to seek professional assistance" to help treat her "exhaustion" and cope with the "stresses in her life."

Us Weekly reported that Moore had tagged along with Willis, Efron and several friends for a post-holidays trip to Turks and Caicos and that Efron and Moore were later seen talking at a party in Los Angeles. A source even told the magazine that Moore had been in pursuit of Efron, following her split from Ashton Kutcher after six years of marriage.

"She calls him and texts him a lot, but he's not interested at all," the source alleged.

In his interview with "Extra," Efron did not respond to those claims. But he did reveal his Valentine's Day plans.

"I might just sit at home and cry," Efron said.
