Larry Hagman at the Fox TCa Party held at Ritz-Carlton Hotel Pasadena, California - 25.07.06

The actor, 75, was admitted to a hospital in Santa Monica shortly after the incident last week (21NOV06).

Hagman, who has battled a series of health issues in recent years and underwent a kidney transplant in 1995, had been complaining of serious headaches in the days leading up to his collapse.

According to US tabloid National Enquirer, he's currently undergoing tests as medics attempt to pinpoint why he blacked out, but the actor seems to be out of danger.

A source says, "He's at home and doing great."
