(Bauer Griffin and Flynet Pictures)
looks typically fierce on the cover of July's W Magazine,
but she's got some competition: Christina Aguilera
is featured on the supplemental "Music & Style" cover, and she's looking the best she has in years.
On the main cover,
a smoky-eyed Knowles glares out from beneath a military cap, pulling the collar of her sheer Marc Jacobs blouse aside for a peek at her decolletage. It's sexy, but nowhere near as arresting as Christina Aguilera's cover,
in which she's covering her essentials with flowers and Lady Godiva hair.
