It wouldn't be Oscars weekend without a popular party courtesy of The Weinstein Company! Oprah Winfrey, Meryl Streep, Taylor Swift, and Chiwetel Ejiofor were just a few of the celebrities who attended the bash at the ritzy Montage in Beverly Hills on Saturday. Most of the stars wore black and white attire to the event. There were a few exceptions, including Karlie Kloss, who donned a formfitting red dress. The A-list has been gearing up for the Oscars all weekend, stepping out for several star-studded parties.
