Fergie, Julianne Hough, Hailee Steinfeld Pictures at Joe Zee Premiere Party

Julianne Hough, Fergie and Hailee Steinfeld, in a Mary Katrantzou skirt, stepped out in LA last night for Elle magazine and the Sundance Channel's premiere of editor Joe Zee's show, All on the Line With Joe Zee, at Soho House. The bash gave Julianne a chance to catch up with her Safe Havenco-star Josh Duhamel, who attended with wife Fergie. Joe's new show is the latest stylish reality show. In each episode, he acts as a mentor to a designer struggling to get their line off the ground.

We spoke with Joe Zee to talk All on the Line well before the program's debut on the Sundance Channel. He said, "It's not the typical portrayal of fashion; it's something that feels real, genuine, and authentic. I was so moved emotionally. There were times when I was on the floor with [the designers], jacket off, sleeves rolled up trying to help. There were also times when I was so mad at the designers, and there were other times when I wanted to hug them. I was so invested in their final outcome."
