Rachel Zoe and husband Rodger Berman stepped out to celebrate the stylist-turned-designer's "Major Must Haves" from Jockey at the Sunset Tower in West Hollywood on Wednesday.
"Rachel and Rodger arrived hand in hand. They mingled together and when Rachel had business to tend to, Rodger still enjoyed himself, chatting with guests and their team," an onlooker tells PEOPLE. "He had a proud eye on Rachel."
The parents to Skyler, 19 months, "worked the room like partners," the source says.
When it came time for Zoe to address the crowd, Berman stood front row and laughed at all her jokes as he sipped on a dirty Martini.
