By now, almost everyone knows Billie Eilish‘s songs. Yep, the singer has practically taken over the music industry and has slayed the charts with her hit singles — but did you guys know that she was actually an actress back in the day? Yep, she secretly starred in Diary of a Wimpy Kid when she was younger, and we are seriously shook over this discovery.

It turns out, the “Bad Guy” songstress didn’t actually have a role in the movie, but instead, she recorded background dialogue for some crowd scenes. And get this — she did that for some other big movies too, including Ramona and Beezus and X-Men!

The 18-year-old previously opened up about the experience to Rolling Stone, and she revealed that before becoming a famous singer, she wanted to be an actress. But she quickly realized it wasn’t for her.

“I went on, like, two auditions. So lame. This creepy, cold room. All these kids that looked exactly the same. Most actor kids are psychopaths,” she explained.

And that’s when she got involved with background vocals.

“I did Diary of a Wimpy KidRamona and Beezus, X-Men,” she added. “It was fun — a bunch of kids in a room yelling random things, and then we’d have a break and get snacks.”

Wow, who knew?! For those who missed it, the discovery comes just days after Lady Gaga said she wanted to be the musician’s mentor. The “Bad Romance” songstress explained that because she felt like she didn’t have anyone looking out for her, she wants to be that person for Billie. And that’s why she decided to reach out to her after the Grammy Awards last year.

“Billie swept a whole bunch of awards so I said, ‘Let’s send some flowers.’ I wrote her a note. For me, it’s healing because it hurt me that I didn’t get that. I’m going to be that for someone else,” she explained during a recent interview with Apple Music. “This idea that we’re rooting for each other, cheering each other on, is so important. I’ve had a harder time with ­older women in terms of having a female ­mentor. Other than Celine Dion and Carole King, it’s proven ­difficult to have someone who would show me the way. So I really hope that young female artists – or young artists of any gender identity or sexual identity – will know that I am rooting for them.”
