Corey Haim’s Recent Drug Tests Revealed

With breaking news that Corey Haim was pronounced dead early this morning, a source on the set of his last film tells ET about his recent drug tests in relation to the project. 

According to the source, Corey was completely drug-free during the production of his most recent movie, 'American Sunset.' We're told that he was tested for insurance purposes because of his public battles with addiction. Testing showed he had no illegal drugs in his system during the four week shoot last May, 2009.

Additionally, the source says the Canadian-born actor was tested again this year. In January 2010 he was allegedly drug tested so he could keep his Visa to stay in the U.S. -- we're told those tests also came back negative.
