The annual Latin Grammys in Las Vegas last night got a dose of star power with appearances from Zoe Saldana, Sofia Vergara, Demi Lovato, Usher, and others. Zoe made a statement in a bold green Elie Saab gown after Gwyneth Paltrow stepped out in a similar dress by the designer yesterday. Sofia and Zoe shared the stage to present an award while Demi took the microphone for a performance with singer Pablo Alboran. Shakira was one of the evening's big winners, since she grabbed the awards for Latin Recording Academy Person of the Year and Best Female Pop Vocal Album. She topped off her exciting night by singing "Antes de las Seis" from her Sale El Sol album. Pitbull and Marc Anthony got together for "Rain Over Me" while Usher showed off his Spanish-speaking skills during a duet with Antony Santos. It was Usher's first time at the show, and he celebrated with an "epic" afterparty at Haze nightclub.
