Is Ryan Gosling Dating Eva Mendes?

Maybe Ryan Gosling, 30, is in crazy, stupid love. The famous-for-being-a-bachelor Hollywood stud appeared with his upcoming A Place Beyond the Pines costar, Eva Mendes, 37, at Disneyland's California Adventure Park on Saturday. The two were photographed cozying up, holding hands, and even kissing.

"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. Actually, the pair "have been friends for a long time," a source revealed. "There's always been this strong chemistry between them ... this was just a matter of time!"

Gosling has been described as someone who simply "worships women" by Drive director Nicolas Winding Refn. He has famously been dubbed a ladies' man and linked to such Hollywood hotties as Rachel McAdams, Sandra Bullock, and Kirsten Dunst. Mendes recently split from her long-term partner, producer George Gargurevich, over the summer.

You can see their onscreen chemistry in 2013, when A Place Beyond the Pines, which is currently filming, will hit theaters. Until then, catch Gosling in Drive, out September 16, and the upcoming Ides of March, also starring another famous ladies' man, George Clooney.
