Bob Barker fainted Thursday while shooting at a gun range in the L.A. area and was taken to Cedars-Sinai Medical Center by ambulance, TMZ reports.

The retired host of "The Price Is Right," 86, was at home resting after being checked out and released, the site reports.

So what happened? Dehydration was to blame, according to Barker's rep, who originally said it was a reaction to medication.
