Ariana Grande’s biggest fan might just be Captain Marvel herself, Brie Larson. The 30-year-old actress, who won her first Oscar for playing the captive mother in the 2015 film “Room,” has openly professed her admiration for the 26-year-old pop star more than once.

Here’s a roundup of four times Larson proved she was the ultimate Ariana Grande fan.

When she called herself a “stan forever”

In May 2019, Larson posted an Instagram video to her story of herself singing Grande’s “My Everything” from her 2014 album of the same name. She captioned it, “stan forever,” Bustle reported.

When she chose “7 Rings” as the musical representation of her style

On March 11, Larson and her stylist, Samantha McMillen sat down for an interview with The Hollywood Reporter. They were asked to fill in the blank to the question, “If your style was a song it would be…” to which Larson immediately started singing, “I see it, I like it, I want it, I got it” from Grande’s 2019 song, “7 Rings.”

When she sang covers of Grande’s songs while playing Nancy Wilson’s guitar

On August 12, 2019, Larson posted another video of herself singing some of her favorite tunes, which included more of Grande’s discography. The actress sang “Needy” from Grande’s 2019 album, “thank u, next” and “God Is A Woman” from her 2018 album, “Sweetener,” according to Entertainment Tonight Canada. The guitar she used to play the tunes on was gifted to her by another singer, Nancy Wilson.

When her “neck was flossin’” in “Carpool Karaoke” with Samuel L. Jackson

“7 Rings” is clearly one of Larson’s favorite songs, because she referenced it again in a “Carpool Karaoke” series’ preview episode with Samuel L. Jackson in March 2019. “Carpool Karaoke” is a segment on “The Late Show with James Corden” but for the Apple TV+ show, Jackson took the wheel as Larson sat shotgun and they both belted out the lyrics.

Because Larson is now an Oscar-winning actress and has a thriving career in film, many people don’t realize she first rose to fame as a teenager trying to make it in the music industry. Her album, “Finally Out of P.E.” was released in 2005 when Larson was only 16, Billboard reported. She eventually let go of her singing aspirations and committed to acting full-time.
