Los Angeles, Dec 13 (IANS): Singer-actress Amy Adams says she sings during stressful situations to calm herself down.

"I've always been sort of nervous and kind of a perfectionist and when I was younger, and it's continued, I kind of sing to myself. I try to do it away from people, (but) on set that's not always possible," femalefirst.co.uk quoted Adams as saying.

"On 'American Hustle' it was a really intense shoot, it was an intense set. So, I went into a corner...and I just started singing 'Dream a little dream (of me)' and (director) David O. Russell said, 'What are you doing?' and I said, 'I'm calming myself down, I sing to myself to calm myself down.'" she added.

The 39-year-old mentions that she encouraged director David O. Russell to try her musical meditation.

"He said, 'Does it work?' and I said, 'Yeah it does work,' and he said, 'What are you singing? Teach me.'

"So David O. Russell and I were sitting on set singing 'Dream a little dream (of me)' and after that anytime we would get stressed you would know because (we would start singing)," Adams said.
