Not all the invited stars walked the red carpet in a McQueen gown, though. Beyonce arrived looking absolutely stunning in Emilio Pucci.
The superstar went for a mermaid-style silhouette (naturally) in black velvet with a high neck, corsetry detailing. Despite wearing a rival designer the heavy embroidery looked to be a nod to McQueen's own final collection.
The design proved to be excellent for posing in but less useful for climbing stairs with the singer leaning on husband Jay-Z to help her up the steps!
