Millie Bobby Brown has become a national treasure. The actor rose to fame for her fan-favorite role as Eleven on the popular Netflix series Stranger Things, but is now known for so much more. The star is also a model, activist, and a singer, and in recent months, she's shown off her amazing voice on more than one occasion. At the Argentina Comic Con on Friday, Brown sang a mash-up of Beyoncé and Katy Perry that proves she is seriously talented.

The performance combined Beyoncé's 2008 rendition of "Ave Maria" with Perry's "Firework", and the result is definitely worth a listen. Brown wasn't just at the convention to belt out some tunes, though; the star also shared some background on her acting career. According to Just Jared, Brown revealed to the audience why she first began acting. "My dad wanted me to leave the house on Saturdays and he told me to look for an activity," she said. "“I immediately wanted to be an actress and use this platform to help people.”

The star has come a long way since her extracurricular acting days, continuing her role in Stranger Things' upcoming second season, landing a Calvin Klein modeling campaign and appearing on magazine covers, and launching the early stages of a singing career.

In the clip from the con, Brown quiets the audience before singing a few lines from the "Ave Maria" rendition. Then, she transitions quickly into the more upbeat "Firework", amidst cheers from the crowd. The whole segment, while short, is enough to show just how powerful Brown's singing voice is. At just 13 years old, she sounds like a professional singer with years of training.

This performance isn't the first time Brown has shown off her pipes. Her coffee-themed version of Adele's "Hello", sung in a Starbucks drive-thru line and posted to Instagram, went viral. She famously rapped Nicki Minaj's verse from "Monster" for Jimmy Fallon. The star loves to cover her fave artists on her own time, and has posted many covers to her YouTube channel and Instagram in the past. While some of these covers have included songs by John Legend, Ed Sheeran, and Jessie J, she can now add Katy Perry and Beyoncé to her repertoire.

While Brown is only just kicking off her acting career, this Comic Con performance might mean more music is in her plans. After all, the star is still super young, and there's plenty of time for an album, or many albums, to be in her future. And even if she doesn't pursue pop, Brown could potentially appear in a musical in the future. Either way, fans are already hoping to hear more of her amazing voice.

There doesn't seem to be much that Brown can't do at this point. She's already a quadruple threat, jumping between acting, modeling, singing, and activism. It seems like every week she breaks out some new talent, but I can't wait to see where her singing will take her next.
