The "Silver Linings Playbook" star said she has zero time for self-obsessed celebrities, reported Daily Star.
"Not to sound rude, but acting is stupid. Everybody's like, 'How can you remain with a level head?' And I'm like, 'Why would I ever get cocky? I'm not saving anybody's life. There are doctors who save lives and firemen who run into burning buildings. I'm making movies. It's stupid," she said.
But despite being underwhelmed by life in Hollywood, the actress said she does sometimes still get starstruck.
"Once I'm obsessed with somebody, I'm terrified of them instantly. I'm not scared of them - I'm scared of me and how I will react.
"Like, for instance, one time someone was introducing me to Bill Maher, and I saw Meryl Streep walk into the room, and I literally put my hand right in Bill Maher's face and said, 'Not now, Bill!' and I just stared at Meryl Streep."
