The music industry's ultimate power couple, Beyonce and Jay-Z, stepped out for the ultra-glam 10th anniversary party for Jay's 40/40 Club on Monday, looking impeccable as always.

The star-studded bash was held at the New York location of the 40/40 Club, and Beyonce wore a plunging, knit Roberto Cavalli gown with cutouts.

Bey always looks gorgeous, but we especially love this white summer evening look. We can't wait to see what the King and Queen of Hip-Hop will wear on their next outing.
