Los Angeles, California - Rebel Wilson dished on pushing herself a little too far after sustaining a concussion on a movie set years ago.

The 42-year-old star had a less than pitch perfect moment back in 2017, according to a new interview with People.

While dishing on her partnership with the Brain Injury Association of America, Wilson revealed that she sustained a brain injury on the set of Isn't It Romantic.

"I'd love to tell you some awesome story where I was doing some cool stunt, but how it happened, it was kind of embarrassing," Wilson shared.

"It was just this little grass hill, and it got a bit slippery with morning dew. Everyone's walking down to the set and I said, 'Careful, guys,' and literally a second after, I slipped, both my feet went out from under me. I fell backwards and hit my head on the grass."

"I lost consciousness for a couple seconds. Then sat up and thought, 'Oh my God, what happened?'" the Bridesmaids star explained.

Wilson, who just welcomed a baby girl, Royce, via surrogate, continued to say that she didn't want to "be a fuss" when an ambulance arrived and decided to go back to work despite learning she had a concussion.

"And so the producers said, 'Do you want to go back to work?' And then I did a 16-hour day."

The Australian star shared that she now understands the importance of taking care of the brain after any sort of injury, a topic she tackles in her next flick, The Almond and the Seahorse.

"That is the most important part of me. Why wouldn't you treat it with the kind of level of respect and get it looked at?" she said.
