Get ready to see a whole other side to Amy Schumer.

The breakout comedian, who is reportedly getting paid $8-10 million to pen her first memoir, spilled exclusively to ET at the 2015 Britannia Awards that she's ready to be an "open book." (Pun totally intended.)

"Believe it or not, there's more to know," the outspoken Emmy Award winner said of her upcoming autobiography. "It's funny, there's a lot of humor in it, but it's also kind of heavy."

According to Publisher's Weekly, the yet-to-be-titled memoir, which will be formatted as a collection of essays, is said to explore Schumer's "childhood, how she got her big break in comedy, her family, and feminism."

"People are going to know everything about me," Schumer added.

At the Britannia Awards over the weekend, the Trainwreck star was honored for her excellence in comedy. Despite the fact that she has won countless awards this year, Schumer revealed that all the accolades still "feels very surreal."

"I think a mistake has been made, and they're going to dump something on my head when I go up," she laughed.

All jokes aside, Schumer revealed the one moment in the past year that exceeded all of her expectations. "Hosting SNL was really a big deal for me," she said. "To get to have my whole family there and my friends, [and] then I was done with the show and we all just got to have a drink together. That was really exciting."
