Ryan Gosling and Eva Mendes were spotted getting cozy at Disneyland over the weekend, sparking rumors that they might be dating.
Us Weekly published photos of the pair holding hands, kissing and going on rides together at the Anaheim, California theme park.
"They were very playful," a witness told Us weekly. "Eva was skipping around like a little girl...She would lean into him and she held his arm the entire time."
A source told the weekly that they have been friends for a long time.
"It hasn't been a secret how excited Eva's been to film with him, and she's always joked with us about how gorgeous he is," the source said. "She's never been shy about having the hots for him!"
Gosling, 30, and Mendes, 37, are currently filming "The Place Beyond the Pines" together. The film also features Rose Byrne, Greta Gerwig and Bradley Cooper.
Between 2005 and 2007, Gosling dated Rachel McAdams, his co-star in "The Notebook." He has also been romantically linked to Sandra Bullock and Kristen Dunst.
In March, Gosling was rumored to be dating actress Olivia Wilde. The actors were reportedly spotted walking hand-in-hand at a Cincinnati aquarium and "getting cozy at a Golden Globes after party" in January.
Mendes is best known for her roles in "Hitch," "2 Fast 2 Furious" and "The Other Guys." The actress recently ended her long-term relationship with producer George Gargurevich.
Gosling recently appeared in the romantic comedy "Crazy, Stupid, Love" opposite Emma Stone. He has also appeared in films like "Half Nelson" and "Blue Valentine." He will next appear opposite George Clooney in the political drama, "The Ides of March," which is slated for release on October 7, 2011.
