They may be big shots in the musical industry now, but every star has had a first time at the Grammys. From Lady Gaga's spiky headdress to Justin Timberlake's perm, here are the most memorable first Grammys appearances.
Famously snubbed for a 2013 Grammy nomination, Bieber's first appearance at the music show was in 2011, where he earned his first nominations for Best New Artist and Best Pop Vocal Album for My World 2.0. Bieber, who performed a medley of hits during that year's show, was beat out in the Best New Artist category by Esperanza Spaulding.
