Olivia Wilde was seen out with 'Blue Valentine' actor Ryan Gosling, sparking rumors that the two stars may be dating.

UsMagazine.com is reporting that Wilde and Gosling were spotted walking hand-in-hand and smiling at each other, at an aquarium in Cincinnati. Gosling was in town for the filming of his new movie 'The Ides of March.'

A video of the couple at the aquarium was taken by a fan of the two actors; the clip has since been removed from YouTube.

Rumors of the new couple had started back in January when the two were seen flirting and getting cozy at a Golden Globes after-party.
