The 2008 American Music Awards, better known as the AMA's, are only two days away and there are two stars who want to make sure their performances are on the dot!
Christina Aguilera and Rihanna were spotted at the NOKIA theater in Los Angeles on Thursday.
Xtina arrived in black and pink attire to rehearse for her opening act! She's set to kick off the star-studded event on Sunday with a medley of her greatest hits. A little bit of Genie in a Bottle, Fighter, Beautiful, Keeps Getting Better and Dirrty!
As for Riri, she arrived at the theater in simple black and white checkers and skinny jeans!
It seems her performance is going to light up the theater, literally! There will be a bit of fire spewing!

they are so boring, i'd rather see britney perform
if only she came, ah that would be amazing she'd burn up the stage
Xtina Aguilera ROCKS she is a mega talented singer and so hot and beautiful! Emma I don't think Britney has it she was a fabricated phenomena pushed by media and supported by the celebrity machine and she fizzled. it's all smoke and mirrors with her and that can only go so far. CHRISTINA CAN SING! CHRISTINA FOREVER!
