Emma Stone realized she suffers from disease after filming ‘humiliating’ fake orgasm scene

Imagine having to fake an orgasm in front of an entire film crew only for you to finally realize that you have a disease that one in 12 Americans have.

That was the 'humiliating' moment Emma Stone had to experience before finding out she has a chronic condition that 28 million people throughout the US have.

Back in 2010, the then 21-year-old starred in rom-com Easy A.

If you haven't seen the film or can't remember what it was like, I'll quickly brief you.

Stone played Olive who lies to her best friend about losing her virginity to a college boy. Christian 'it' girl Marianne (played by Amanda Bynes) overhears their conversation and then the rumor spreads throughout the entire school.

She then decides to embrace her newfound bad reputation and helps out male students in the school who are being bullied by pretending she had sex with them.

The film also stars by Penn Badgley, before his time on the hit Netflix series You.

But it is when her friend Brandon, played by Dan Byrd, approaches her to help him that it got real for Stone - who is now 35-years-old.

Olive and Brandon plot to make people believe they are sleeping together in order for bullies to leave Byrd's character alone.

To make them believe it is real they wait to do it at a party, and the shooting for the scene took place on the second day.

While on set, Stone is frantically jumping around trying to simulate them both having sex so that partygoers would hear, and it was at that point that she discovered she actually had the common and lung disease, asthma.

Imagine going 21 years without knowing you had the chronic condition...

Recalling the incident to MTV while promoting the film 14 years ago, she said: "Oh, for the love, I can't even simulate sex without dying!

"I had a little asthma attack, without any prior knowledge that I had asthma, during the scene where we had to jump up and down for hours and hours screaming and yelling on the bed."

Stone went on to explain how 'humiliated' she was for it to happen in front of her peers - thinking they'd all be judging her.

She continued: "[It] was humiliating, because it was the second day of shooting.

"Here's what it's going to be like the whole movie, as I'm breathing into an oxygen tank.

"The crew was like, 'She's going to be a real blast. Wow. Amazing. A 20-year-old having an asthma attack.'"

Well, I don't think anyone would have really judged her at the time, and they certainly can't anymore having scooped an Academy Award for Best Actress back in 2017 for her role as Mia in Damien Chazelle's La La Land.

Then again, earlier this year she picked up the same accolade this time for her role as Bella Baxter in Poor Things.
