Amy Adams broke down in tears when asked about Philip Seymour Hoffman.

The 39-year-old 'American Hustle' actress, who co-starred with the late actor in 'The Master' in 2012 and 'Doubt' in 2008, started sobbing and struggled to speak while filming an appearance on 'Inside the Actors Studio' in New York City on Wednesday (05.02.14).

A source told ''(The show's host) James Lipton asked her about working with Philip on 'Doubt' and 'The Master.' It hit a nerve with her. [Adams] was sobbing and couldn't finish most of her sentences.''

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

The interview will air on Bravo in the US on February 19.

Amy signed on to star in 'Ezekiel Moss,' the follow-up to Philip's 2010 directorial debut, 'Jack Goes Boating,' alongside Jake Gyllenhaal just last week.

The 'Capote' star was found dead in his apartment in the West Village in New York on Sunday (02.02.14) from an apparent heroin overdose.

A private wake for the 46-year-old Oscar-winner, who sought treatment in rehab in May 2013 after 23 years of sobriety, is set to take place at Frank E. Campbell Funeral home in Manhattan today (06.02.14) ahead of his funeral at Loyola Roman Catholic Church on Friday morning (07.02.14).
