Before she was touring with the Biebs, making hit records and hilariously singing hip-hop songs with Jimmy Fallon like it's NBD, Ariana Grande was just another girl making YouTube videos in her bedroom.
Though you probably know her best for her more recent pop hits, the "Almost Is Never Enough" singer has an archive of amazing covers that we felt we needed to unearth -- from before she had a record deal. Check out our top 8 picks below for proof that the "Sam & Cat" actress was always a star in the making.
1. "I Believe in You and Me" by Whitney Houston
This stripped-down Whitney Houston tribute is hauntingly gorgeous. We dare you not get goosebumps.
2. "If I Ain't Got You" by Alicia Keys
Sitting on the floor on her New York apartment (sporting dark red hair from her "Victorious" days), this one's an oldie but goodie.
3. "If I Were a Boy" by Beyoncé
Taking on Queen Bey isn't an easy feat, but Ari hits those notes like nobody's business.
4. "Bleeding Love" by Leona Lewis
In further proof that she loves her fans, Ariana adorably dedicated this cover to her fan-of-the-month, who requested the song for her birthday. "She already went to bed so she thinks that I forgot about her," says Ariana in the video. "But I didn't."
5. "Unwritten" by Natasha Bedingfield
We can't decide what we like more: Ariana covering the theme song from "The Hills" or the surprise appearance from her puppy, Coco.
6. "Teenage Dream" by Katy Perry
If this doesn't make you want to drive with the windows down, music blasting, with your best friends while drinking Slurpees, we don't know what will.
7. "Born This Way/Express Yourself" by Lady Gaga/Madonna
What happens when Ari takes on two queens of pop? Mashup magic, that's what.
8. "Rolling in the Deep" by Adele
Girlfriend slays it. That's all.
