Amy Adams is one of the first people in the movie business to publicly discuss the recent passing of Academy-Award winner Philip Seymour Hoffman.

But she didn't find it easy.

While appearing on Inside The Actors Studio this past Wednesday (Feb 5th), the 39 year-old broke down into a stream of tears when the conversation turned to Hoffman's death.

Adams, who co-starred with the 46 year-old in 2008's 'No Doubt' and 2012's 'The Master', began to get upset when the host James Lipton asked about her experience working with him.

"James Lipton asked her about working with Philip on Doubt and The Master. It hit a nerve with her," an insider told Us Weekly. "[Adams] was sobbing and couldn't finish most of her sentences."

"Amy talked about how he was the greatest actor she had worked with, and couldn't even tell stories about him without crying," the source revealed. "She said to the audience of acting students 'I wish you all could have had the chance to work with him.'"

Hoffman and Adams received Oscar nominations on both occasions of working together.

The 'Capote' actor was found dead in his Manhattan apartment, at 35 Bethune St. in the West Village, by screenwriter David Bar Katz, on the floor of his bathroom with a syringe still lodged in his left arm.

On Monday, police sources revealed exactly how much of the illegal substance was in Hoffman's apartment. 5 empty bags and 65 full bags of heroin were removed from the New Yorker's home by the authorities.

The New Yorker actor will be laid to rest in a New York City private ceremony this Friday (Feb 7th), only close friends and family will be invited to attend the funeral, and another memorial service is being planned to take place later this month, also in New York.

Amy's Inside The Actors Studio interview will air on February 19th at 8 p.m. EST on Bravo.
