After hitting Sau Paolo Fashion Week in Brazil last night, Ashton Kutcher immediately caught a flight back to Los Angeles to support his estranged wife, Demi Moore. His soon-to-be ex was hospitalized for exhaustion this past week, and upon hearing about Demi’s recent health troubles, a worried Ashton headed right home.

“Ashton is deeply concerned for Demi,” a source told People magazine. “He still cares about her and wants what’s best for her.”

Though Demi has since been released from the hospital, its been speculated that exhaustion isn’t the only thing that she’s being treated for. According to additional reports, the actress is also being treated for an eating disorder.

Although Demi’s camp has already stated that the star will “seek professional assistance to treat her exhaustion and improve her overall health,” within the coming weeks, I have a feeling even more information about Demi’s condition will come to light.
