The Friends with Benefits star told GQ that she tries to maintain a sense of humour about her life and work.
Kunis said: "I love what I do, but my theory is that it's people who doubt what they do and want to prove it to you, they're like, 'It's art. I create art. It's art, art, art'.
"I'm like, 'Holy s**t, are you f**king kidding me?' I run around and pretend I'm someone else for 12 hours; I record [the voice of Meg for] Family Guy. Then I get to go home and watch Jersey Shore."
This week, Kunis declared that she's very much looking forward to attending Friday's Marine Corps Ball with Afghanistan War veteran Sergeant Scott Moore.
The actress will next co-star with Mark Wahlberg in director Seth MacFarlane's comedy Ted, which opens on July 13, 2012 in the US and August 3, 2012 in the UK.
