House actress Olivia Wilde is newly single, but recently she's been spending time in the company of a new guy – Ryan Gosling. On Feb. 27, the pair were spotted at Nada, a trendy Mexican restaurant in downtown Cincinnati for what an onlooker describes as "a cute, friendly brunch." (Gosling is in Cincinnati filming The Ides of March with George Clooney.) After brunch Wilde, 26, and Gosling, 30, headed across the river to spend the afternoon at an aquarium in Newport, Ky. Dressed down in casual clothes, they waited in line with the other guests and blended in nicely. "They didn't seek any special treatment or behind-the-scenes access," says Rodger Pille, a spokesman for the aquarium. "They paid for their tickets and enjoyed, among other things, our current star animal, Mighty Mike, a 14-foot long American alligator." Wilde's rep had no comment. Gosling's rep could not be reached for comment.
