The musical duo, who rocked the world with their recent pregnancy announcement, surprised and delighted guests at The Weinstein Company's pre-Oscars party last night when they made a welcome appearance. Beyonce was positively glowing as she greeted guests at the event, which was held at the Montage Beverly Hills with cocktails on hand by Grey Goose. She wore a form-fitting Nicole Miller dark green dress ($420; nicolemiller.com) with a stack of gem-encrusted bracelets and a statement necklace. The pop star, who recently revealed she is expecting twins, had her hair styled in loose waves around her shoulders for the visit.
