Ryan Gosling's aquarium date with Olivia Wilde

Ryan Gosling is reportedly dating Olivia Wilde.

The 'Blue Valentine' actor was spotted enjoying a date with the recently separated 'Tron: Legacy' actress at an aquarium in Cincinnati, Ohio, where he is currently shooting 'The Ideas of March' with George Clooney.

A source who saw the pair said they were holding hands and looked "relaxed and happy" as they spent time walking around the aquarium.

A friend of Olivia's recently claimed the 26-year-old actress was hoping to "sow her wild oats" after splitting with husband Tao Ruspoli after eight years of marriage.

A friend said: "Olivia got married really young. She's done a lot of growing since then, just like anyone would... they've just grown in different directions."

Another insider added: "They have been separated for a while. It was Olivia's decision...for the typical Hollywood reasons.

"Her career has exploded and she saw being married is not as much fun. She feels she missed out on being single getting married so young, and wants to sow her wild oats."

Olivia and filmmaker Tao - son of the late Italian Prince Dado Ruspoli - met when she was 18 and the pair got married after just six months of dating.

Ryan has previously dated Sandra Bullock and Rachel McAdams.
