The 2012 Billboard Music Awards take place in Las Vegas on Sunday night, bringing together the best and brightest artists that the topped the Billboard charts during the past year!
In honor of the big night, our friends over at Snakkle.com dug up some photos of our favorite music stars, before they were famous!
Adele
She's already won a ton of Grammys and is up for an amazing 18 awards tonight -- including Top Artist and Top Female Artist -- but before Adele developed that powerhouse voice, she was just a little girl with a plastic mini-guitar and big dreams!
Who ever would have thought that this sweet tyke with the messy hair would record an album that's gone on to sell over 9 million copies in the U.S. alone?
Lady Gaga
While she may be best known now for her interesting fashion choices -- meat dress, anyone? -- Lady Gaga was once just young Stefani Germanotta, rocking her First Communion gown!
The supremely talented "Mother Monster" is nominated in 10 categories including Top Artist, where she's up against superstars Rihanna, Katy Perry, Lil Wayne and Adele.
Justin Bieber
He's only been on the planet for 18 years, but in that short time Justin Bieber has gone from adorable little Canadian baby to one of the biggest popstars in the world!
The "Boyfriend" singer is set to perform at the awards show, where he's also up for Top Male Artist. Will he walk the red carpet with girlfriend Selena Gomez?
Lil Wayne
Before the diamond grills and saggy pants, Lil Wayne was a 7th grader at McMain Magnet School in New Orleans who was already on his way to a successful music career -- he'd made his recording debut at age 9!
The hugely successful rapper is nominated for 10 Billboard Awards including Top Artist, Top Billboard 200 Album and is going up against The Biebs, Bruno Mars, Chris Brown and Drake for Top Male Artist.
