Emma Stone became so passionate during a sex scene for new movie "Easy A," she began hyperventilating and suffered an asthma attack.
 
The actress stars as a high school student who pretends to have loud sex with a number of male pupils so they look "cool" in the teen comedy alongside Penn Badgley.
 
But on her second day of shooting, Stone was left red-faced after a medical crew had to rush to her side when she started breathing heavily during the passionate scene.
 
She tells MTV News, "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. (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.'"
