Hate It or Love It? Beyoncé Attends the Cotto/Alvarez Fight in Michael Costello [Photos]

Beyoncé attended last night’s Cotto vs. Alvarez boxing match in Las Vegas.

She wore a silk Michael Costello gown featuring a plunging neckline.

She posed it up with Kelly Rowland (above) who looked equally as amazing.

What do you think of Bey’s look?
