Photos of Rihanna and Chris Brown Rehearsing For the American Music Awards

Rihanna looked preppy-sexy at the rehearsals for Sunday's American Music Awards in LA yesterday. While she and Chris Brown kept their dancing separate, they're smoking when on stage together, so hopefully we'll get to see some of that too. With Christina kicking off the show and even rumors of a Britney appearance, the awards should be extra exciting this year, so be sure to stick around on Sunday night while Fab and Bella bring their live red carpet love or or hate it polls!
