Ashton Kutcher was photographed at LAX yesterday after leaving Sao Paulo, Brazil.  While Ashton was abroad, he watched a fashion show, shot a campaign for Colcci with supermodel Alessandra Ambrosio, and went partying.

Meanwhile Demi Moore was losing it. The 49 year-old actress checked into a hospital Monday after allegedly having seizures after inhaling too much nitrous oxide.

A source says: “He cares a lot for her. He’s very concerned and will always support her.”

Ashton needs to be photographed by Demi’s side for people to understand that he cares about his ex-wife. We’re wishing Demi a speedy recovery.
