Demi Moore Has Ashton Kutcher 'Deeply Concerned'

'He still cares about her and wants the best for her,' a source tells People following Moore's hospitalization.

In the days following Demi Moore's surprising hospitalization Monday night, the details that have emerged are even more perplexing, particularly the latest reports that Moore was inhaling nitrous oxide from aerosol cans, also known as whip-its, the night the 911 call was placed from her home in Los Angeles.

And although Moore has been released from the hospital, People magazine reports that the actress' health scare has her soon-to-be ex-husband Ashton Kutcher very worried about his wife of six years.

"Ashton is deeply concerned for Demi," a source told the magazine. "He still cares about her and wants the best for her. But their marriage is ending and they are both moving on with their lives."

Kutcher has yet to make any official statement about Moore, nor has he expressed anything about the matter via his frequently updated Twitter account. The "Two and a Half Men" star was out of the country working on an ad campaign when news of Moore's hospitalization broke. He is reportedly back in L.A. to return to work on "Men."

The theories about why Moore turned to nitrous oxide in the first place all relate back to her very public and emotional split from Kutcher back in November, when Moore announced the breakup with "sadness and a heavy heart" after months of not-so-quiet rumblings that her husband had been unfaithful.

Demi Moore's hospitalization caps a rough patch for the actress.

Friends have said that shortly after her split with Kutcher, the 49-year-old began to have trouble sleeping and developed a severe problem with prescription drugs.
