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.
Britney's first Grammy Awards ended in an upset when her Mouseketeer rival, Christina Aguilera, snagged the Best New Artist award from right under her nose. She's been nominated for a total of eight Grammys, but the only one she's won was Best Dance Recording for 2005's "Toxic."
