Nina Dobrev and Ian Somerhalder were side by side last night to attend the Met Gala afterparty at the Top of the Standard. Nina wore a long Donna Karan gown for fashion's biggest evening, and her boyfriend Ian was dapper in his own tux. Ian and Nina are together again after work took him to Spain last week. Ian wasn't, though, by Nina's side on the red carpet as she arrived for the main event at the Metropolitan Museum of Art. Ian seemed to revel in the exciting star sightings offered last night. He tweeted from the Standard, "You know you are at a very cool party when Mick Jagger is dancing by himself next to you chilling and grooving in his own world."
