Emma Roberts and More Hit Nylon Magazine’s Young Hollywood Party

Twentysomething actors, such as "Scream 4's" Emma Roberts, "Glee's" Chord Overstreet, and Hollywood offspring Rumer Willis, made the Roosevelt Hotel in Hollywood the place to be Wednesday night, as they toasted Nylon magazine's annual Young Hollywood Issue. Roberts and Overstreet, who are reportedly dating again after being broken up for three months earlier this year, went casual chic. The stylish Roberts, 21, donned a black-and-white striped cocktail dress by Rachel Zoe, with her hair in curls, while 23-year-old Overstreet opted for a tough black leather jacket and T-shirt over jeans. If Overstreet was in a particularly celebratory mood, it was because Wednesday marked the final day of filming for the third season of "Glee."

Willis also went with a black and white look, but she didn't pull it off as well as Roberts. The 23-year-old rocked a layered ensemble that included an LBD, a long white shirtdress, a dark blazer, and black boots, as well as a tightly curled 'do. What do you think of her pajama-inspired look?

Newlyweds Nikki Reed and Paul McDonald were also on the scene. The "Twilight" starlet, 23, and her "American Idol" hubby, 27, sported a rose-colored dress with cutouts in the midriff (her) and a T-shirt-and-blazer combo over dark skinny pants (him). McDonald tweeted, "I must say the LA party scene is quite different from drinking PBR's with my buds in Alabama." Um, just a little!
