Meanwhile, Posen took to his Instagram account to explain how he wanted to share his latest work with the help of his "dear friend."
"For #Fw18 I wanted to present my collection in an intimate portfolio of my dear friend @katieholmes212," he captioned a black-and-white pic of the two. "Thank you @katieholmes212 for capturing the magic two days we had shooting The New #ZacPosen collection!"
He also shared behind-the-scenes snippets of Holmes in an exquisite red strapless gown, a dramatic hot pink creation and a mauve-colored gown with a massive train, as well as additional videos of Holmes during the shoot.
"I wanted to create something intimate and personal, A project that marks this time and our Beautiful friendship! I will cherish these images forever! Thank you @katieholmes212 and the whole #zacposen family!" Posen captioned another snap.
The night before, Holmes and Jamie Foxx made a rare appearance together at the Clive Davis and the Recording Academy’s Pre-GRAMMY Gala in New York City. The elusive couple appeared smitten with each other and laughed and goofed off together
