Amy Adams gave Justin Timberlake the kiss of life, he has revealed.
The pair were filming sports drama Trouble With The Curve on a frozen lake at the Blue Ridge Mountains in Georgia, USA, with producer and lead actor Clint Eastwood when the singer began to lose consciousness due to the extreme cold.
"We shot the scene in the Blue Ridge Mountains and the water was just below 50 degrees. It was freezing," he told Entertainment Tonight.
Justin, who is engaged to Jessica Biel, continued: "Amy actually saved my life. Unbeknownst to me, I was turning blue and couldn't process a thought, so she actually saved my life. I owe Amy Adams my life."
Amy added: "Some people call it mouth-to-mouth, some people call it kissing - anyway, it's nice work if you can get it!"
Trouble With The Curve, which opens in UK cinemas on November 30, is Clint's first acting job since 2008's Gran Torino and his first acting role in a film he did not direct since 1993's In The Line Of Fire.
