Mary-Kate and Ashley Olsen supported their sister, Elizabeth, celebrating her Nylon magazine cover during a Armani Exchange-hosted private dinner and party. The sisters all hugged when they arrived at Sons of Essex, though Mary-Kate and Ashley made sure to stay out of the spotlight so Lizzie could have her moment. “Mary-Kate and Ashley sat on either side of Lizzie and would often raise their red wine glasses to toast their sister’s success,” a source says of the trio, who later sat down for dinner. – Jennifer Garcia
