Kevin Costner was treated in a Los Angeles hospital this week (06-07Jan08), after calling emergency services following a fainting spell.
The 53-year-old Oscar winner called 911 on Tuesday morning (06Jan08) complaining of dizziness while driving to a meeting.
Paramedics raced to the scene and found Costner vomiting by the side of the road, according to TMZ.com.
He was reportedly taken to Cedars-Sinai Medical Center and held overnight for tests.
Costner's publicist tells WENN, "Mr. Costner experienced some light-headedness while he was driving, was checked out at the hospital and released after tests found that everything was normal."
