McCollough and Hernandez will be taking Australian ingenue Isabel Lucas, who attended last year's gala as a guest of Louis Vuitton. Lucas's star shines bright in the land Down Under, and it's been getting brighter in the United States since she starred in 2009's Transformers: Revenge of the Fallen. Since then she's also been tapped for Steven Spielberg's miniseries The Pacific and played the role of Athena in last year's Immortals.
The only other designer whose date has been revealed is Joseph Altuzarra, who will be dressing and escorting singer Lana Del Rey. She recently appeared on the covers of British Vogue and French Glamour. This will be her first time at a Met Gala.
Last year, Altuzarra walked the red carpet with Arizona Muse, while Lazaro and Hernandez took Kristen Stewart.
