Ryan Gosling is reportedly dating Eva Mendes.

The Hollywood heartthrob and the stunning actress - who recently shot new movie 'The Place Beyond the Pines' together - were seen holding hands and canoodling during a trip to Disneyland, California, over the weekend.

An onlooker told People magazine: "They looked relaxed and seemed to be having a fun time together. Like a dating couple, they always walked very closely, holding hands and their arms touching side-by-side. 

"Ryan seemed to pay a lot of attention to her. He would glance over and look her in the face as they walked through the crowds making sure she was okay." 

After enjoying the rides and amusement attractions, Ryan, 30, and Eva, 37, watched the World of Color Spectacular water show.

It is believed the romance began on the set of the film as they got on so well together and continued to see each other once shooting had finished.

A source said: "Ryan and Eva have spent a lot of time together on set. They have great chemistry and seem to enjoy filming together. They seem to be good friends and always laugh together."
