At the World Music Awards in Monaco we already saw Avril Lavigne's red carpet arrival, but here she is in a rehearsal before the big show. Celine Dion was also there, Taking Chances with a risque silver dress...hahaha, sorry, I couldn't resist :) Rihanna sang too. There are some pictures of her rehearsing (in plaid in the thumbnails) and performing (in black, above).It looks like this was an amazing event! Click on thumbnails to enlarge.
