LOS ANGELES-Emma Stone can't believe women struggled to earn as much as men in Hollywood and throughout the US Jennifer Lawrence and Emma Watson have been vocal proponents of actresses being paid the same amount of money as their male counterparts for equal work, and now the 27-year-old has opened up on the subject.

Although she insists she has received the same salary as her male co-stars for her past few films, Emma is concerned she might be one of the only women in Hollywood getting a fair deal.

"We should all be treated fairly and paid fairly," she tells Vogue magazine. "I've been lucky enough to have equal pay to my male co-stars... I've had pay equal to my male co-stars in the past few films. But our industry ebbs and flows in a way that's like, 'How much are you bringing into the box office? How much are you the draw or is the other person the draw?'"

And she admits pay negotiation conversations are never easy, once her lawyer and agent get involved. "I felt uncomfortable talking to my agent or lawyer about it because I was like, 'Do people want to see me as much as they want to see Steve Carell?'" she continues. "It's a weird conversation to have because it's trying to see oneself from the outside.

"(But) what are we (women) at (nationally)?" she muses. "Seventy-nine cents to the dollar? It's insane. There's no excuse for it anymore."

The Birdman star has experienced an uptick in her career over the past few years, but she still worries it could all go downhill - fast.

"(I went from thinking), 'What can I get? to 'What do I want?'," she says. "(However), you always feel a little bit like... you could again be an outsider, that something could make people never want to hire you again."
