Hollywood beauty Reese Witherspoon was left a sweating wreck during the filming of upcoming Johnny Cash biopic, when she had to sing in front of a crowd.

Witherspoon gets nervous in large groups of people and found her role playing Cash's wife JUNE CARTER CASH in Walk the Line a difficult challenge.

She says, "I have extreme anxiety in front of crowds and I have to sing in this new Johnny Cash movie.

"I sweat in places I didn't know you could sweat. But nervousness is sometimes a good thing. It pushes you forward."
