Willow Shields plays the fashion games

She may be only 14, but Willow Shields knows how to strike a pose. "The Hunger Games" star (she plays little sister Primrose to Jennifer Lawrence's Katniss), turned up at Peter Som on Friday morning -- her first fashion show. Happily mugging for the paparazzi, hands on hips, Shields said: "I learned how to pose on the red carpet."

Wearing Som's dark, tailored dress with appliqued flowers, Shields was clearly enjoying the moment. "It's so exciting to be wearing something very sophisticated, and it's very different. I've gone from being very grungy to a real fashion person." We'll see more of her during the week, because she's also planning to attend Christian Siriano and Betsey Johnson's shows.

Zosia Mamet dismisses double 'do-over

Rumor had it that HBO "Girls" stars Zosia Mamet and Lena Dunham dyed their hair a stark, whitish blonde at the same time. "We didn't do it together," said Mamet, who screeched into the Rebecca Minkoff show Friday seconds before it started, blustering (with a few choice expletives) about the traffic. "I did it about a week and a half ago," she said, while Dunham debuted the 'do much earlier. As for the fashion, Mamet said she and the designer "are dear friends. We wear her clothes a lot on the show, but not like this," she said, referring to her own smart ensemble that included a tweedy skirt and leather jacket, along with jewels that were "all from Becky."
