It was Ashley Greene's time to shine recently, at West Hollywood hotspot Chateau Marmont, where the Twilight star was celebrated for being on the cover of Nylon magazine's denim issue, wearing jean Element Eden "Idol" shorts.

Joined by other folks, including Chord Overstreet, Brent Bolthouse, stylist Johnny Wujek and the magazine's Editor-in-Chief Marvin Scott Jarrett, the actress "seemed in great spirits," an onlooker tells PEOPLE, adding, "She was mingling with guests."

Attendees at the fancy dinner fête were offered wedge salad, steak, fries, grilled branzino and corn polenta. And although the meal had bottles of vodka flowing, a different source says, "Ashley was not seen drinking."

Greene happily discussed fashion with media who stopped her for an interview, but questions related to the scandal between her costars Robert Pattinson and Kristen Stewart were not allowed by the actress's publicist.
