The star, who made her professional acting debut at just 15, told Esquire UK that the close relationships she cultivates with her co-stars prevent love scenes from ever feeling awkward.
"[My co-stars are] all mates, that's the thing," Cornish insisted. "So I'm lucky."
She continued: "With friends, if someone's pants don't come off properly, or if something gets stuck, you just end up giggling."
The star also explained that she has a wide variety of diverse interests outside of her profession.
"I'm into painting and street art and I'm a musician, I play piano," Cornish remarked. "I love taking pictures or filming things documentary style. And I'm definitely active - I love surfing."
Cornish recently told DS that her W.E director Madonna is "definitely determined and quite a visionary".
Last month, the star suggested that meeting two-time Oscar-winner Robert De Niro on the set of Limitless was "amazing".
W.E is expected to premiere in US and UK cinemas later this year.
