Emma Stone worried people will "joke with her" by leaving money around

Discussing her revelation, which she made to talk show host David Letterman, she said: "I wasn't even going to talk about that [on Letterman], but then he was telling me a true story about a woman on his show that died who taps him on the shoulder and talks to him a bit.

"I completely regret telling that story about my dead grandfather that leaves quarters because now I feel people are just going to leave quarters around to f**k with me.

"It was this sweet family thing where my mom found them, my aunt found them, and now it's going to be like, 'Oh look, there's a quarter!' Ugh."

The 25-year-old beauty - who is in a relationship with Andrew Garfield - thinks it is possible to believe in other-worldly experiences while also retaining an element of doubt.

She told The Daily Beast: "I've been to a medium and a psychic... I am a total skeptic, and a believer. Both things co-exist."
