Olivia Munn is set to recapture some of the magic of "The Devil Wears Prada" when that film's writer and director reunite for "I Don't Know How She Does It," starring Munn and Sarah Jessica Parker.

"It's been amazing, (Sarah)'s the girlfriend that you would hope that she would be," Munn told us before the Jill Stuart show at Mercedes-Benz Fashion Week. "She's literally the best friend that you would ever want. She's the sweetest girlfriend."

"She has such style that I don't even go there yet with her," Munn added. "She's so easy with everything, it just kind of just hangs on her so well and I love being around her. We hang out and have lunches together and she gives me great advice."

Before you sound the BFF alert, Parker isn't the only celebrity whom the actress admires. Munn said, "I love what Rachel Bilson wears all the time. She always looks great."

The actress shared the love and also gushed about Jill Stuart's designs. "I love that she's so pulled together, but it feels very effortless as well. It's still very tailored and ladylike. I feel put together but not done up. I love prints and I like things that look old-school. Jill herself is wearing a dress with a print on it. I want that dress, I would have been wearing that."

The 30-year-old is a Fashion Week virgin and explained that she didn't make a special trip to Manhattan for the runway spectacle. "This is my very first fashion show, ever. I'm here to shoot the movie so I'm in New York until the summer."

Munn rocked strappy YSL heels and described her patterned ensemble. "I'm really obsessed with mixing prints together. I'm wearing this amazing Jill Stuart navy dress with this vintage, pink belt that I have and purple shoes. I like mixing colors."

The rising star may not yet be a household name but she already seemed to be very "Hollywood". When StyleList asked about the designer of Munn's earrings, she breezily responded, "I don't know, I'll ask my stylist for you."
