Beyoncésque 

adj. Used to describe female vocalists who appear to imitate Beyoncé in their performance(s) through their overall look, styling, mannerisms, dances, or sound. Usually used to describe vocalists in the R&B genre, but not always.

Amerie used to have such a unique sound and look, but lately she seems so Beyoncésque! I'm sure she'll snap out of it soon.
