Brie Larson has already won a handful of awards this year for her performance in the heartbreaking thriller Room, so you’d think she’d have the hang of the awards show thing by now.

Turns out, Larson nearly missed her win at Sunday’s Golden Globe Awards because she was in the ladies’ room!

“All I remember is I needed to go to the bathroom,” the 26-year-old actress told ET backstage. “I went to the bathroom and as I was leaving, Helen Mirren was like, 'Don't go right now. Your category is coming up.' And I said, 'No it's not. I've got like an hour to go.' Then Kate Winslet was like, 'Don't go right now.' I said, 'I have to. I still have an hour.' I wasn't looking at the clock, which was a big problem.”

Thankfully, Larson made it back to her chair just before her category was called -- saving her from facing the same embarrassing fate as Chicago Hope star Christine Lahti in 1998 -- and admitted that the time crunch kept her from getting too nervous before her name was announced.

“[It was] good because I didn't think about it,” she said. “Bad, because I was about to reapply Chapstick and was like, ‘Oh.’”

Larson spoke to ET on the red carpet about getting Golden Globes tips from her friend and “mentor,” Emma Stone, and we’re hoping she took her advice after that last-minute bathroom run!

“She told me to wash my hands a lot, so I don’t get pink eye,” she revealed, adding that hand sanitizer was also among Stone’s recommendations for awards essentials. “It’s actually a very good [tip], you don’t think about it.”
