Emma Stone was left red faced after meeting Cameron Crowe - she burst into tears in front of the director.
She tells Britain's Stylist magazine, "I zen myself up these days, and I've got pretty good at it. The only time I flip out is when I'm not prepared. If I'm caught off guard, I can't help it; I start gasping for air.
"I've actually cried in front of three people because I was so blown away to be in their presence: Cameron Crowe, Lorne Michaels and Tom Hanks.
"(Hanks) didn't see, thank goodness. I turned and rushed away, and he'll only know about it if he reads this interview. However, with Cameron Crowe, I cried right in front of him whilst shaking his hand. How embarrassing."
