Emma Stone discovered she had underlying health condition whilst filming sex scene

Filming a sex scene is weird enough as it is, but imagine if you found out you had a medical condition in the process...

Well, that's exactly what happened to Emma Stone while in the middle of filming Easy A.

The star opened up about the embarrassing moment when she got more than she bargained for during the intimate scene which featured a fake orgasm.

She was playing the role of Olive Penderghast in the 2010 film which was inspired by the novel The Scarlet Letter.

During the flick Olive exaggerates her sexual experiences, but unfortunately for her, rumours soon spread.

Her friend Brandon asks for help by pretending to sleep together so bullies will leave him alone instead of picking on him for being gay.

In order to make things believable, the duo had to noisily pretend to get it on at a party.

It was during this scene that Emma's medical discovery was made.

The actors were jumping around on the bed, making a lot of noise when all of the action caused Emma to have an asthma attack.

"Oh, for the love, I can't even simulate sex without dying!" she told MTV at the time.

Then aged 20, she had gone through life so far not realising she had the dangerous condition.

"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."

She went on to admit it was 'humiliating', and to make matters worse it happened on only the second day of filming.

Emma added: "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'."

Emma went on to film even more explicit scenes in the award-winning Poor Things, which saw her landing an Oscar for her efforts.

It seems to have all worked out okay in the end despite her initial embarrassment early in her career, and there's no doubt she gone on to cement her success on the big screen.
