"She was fantastic," Adams said. "She was also so thrilled by it. They now call her Sister Hollywood. She was at the premiere and stayed longer than I did."
When Streep complimented Adams' performance, the latter dead-panned, "It takes a bitch to play virtue."
Although both actresses recently starred in musicals -- Streep in "Mamma Mia" and Adams in "Enchanted" -- there was no song and dance on the set of "Doubt."
"I kept on hoping," Adams said. "But there was no 'Dancing Queen' from Meryl."
Jokes aside, Adams admitted to being nervous about working with Streep and Hoffman.
"I wanted to be a good scene partner," she said. "Here we have Meryl Streep and Phillip Seymour Hoffman. We know what they're capable of, but there was a moment when I had to look and say, 'I will never be Meryl Streep.' That was me coming to terms with how brilliant she is -- to be in awe, but not intimidated."
Streep wryly shrugged off the praise with "all I want is respect ... and coffee ... regular coffee."
