Simply beautiful is the fitting term.
Check out the 3 of the 5 original 'Destiny's Child' members: Beyonce, Kelly Rowland, and Michelle Williams. All three looked absolutely hot in their own way at the 2011 Billboard Awards.
BEYONCE's performance of 'Who Run The World (Girls)' was electrifying, as was her outfit (check pic below).
Kelly Rowland was flying high on 'Motivation' wearing what I believe was a fuchsia Herve Leger dress.
Michelle Williams looked sensual and somewhat mysterious (her serene, beautiful facial structure with her sequined and playful dress), but still HOTT nevertheless.
I see you Bey... I wonder how she got that outfit on in the first place...
