Comedian Amy Schumer realised she'd conquered her pre-show nerves when she was no longer "on the toilet until the last minute".
The Trainwreck star began her career on the stage and she still likes to get behind the microphone when she has the time. These days she doesn't get anxious before a set, although that hasn't always been the case.
"I still love it and I get excited when I have a new joke, but I'm not nervous anymore, like ever," she told Britain's Heat magazine. "I used to be really nervous - on the toilet until the last minute. But now, performing to 10,000 people doesn't faze me at all."
"When I started out, I wanted to shock. Open mic in America is just other comedians waiting to go on stage, no one is really listening. It's a miserable group, so you have to shock and surprise people into laughing."
Movie Trainwreck shot Amy into the limelight, and it's also scored her a best comedy/musical actress Golden Globe nomination.
She's also known for a stunt she pulled in front of Kanye West and Kim Kardashian - she pretended to fall next to them on the red carpet because she thought it'd be funny.
Her flamboyant and body confident attitude has gone down well with fans, everyday people and A-listers alike. In fact, the mass of celebrities who are clamouring to say nice things about her still shocks Amy.
"That's the coolest thing, it's people I've idolised who are my fans," she said. "Julia Louis-Dreyfus, Patricia Arquette and Tina Fey - having them agree to be in a scene and say they think what I'm doing is awesome. Even Diddy has tweeted that he loves the show. And Madonna is into it. So weird."
