Another love match in the Magic Kingdom!

On Saturday, Ryan Gosling and Eva Mendes hit Disneyland in Anaheim, Calif. for a fun day of rides, junk food...and lots and lots of PDA!

As exclusive Us Weekly photos show, Gosling, 30, and Mendes, 37, held hands, kissed and had a ball together.

"They were very playful," an observer tells Us. "Eva was skipping around like a little girl...She would lean into him and she held his arm the entire time."

And the sexy twosome did Disneyland right -- riding the Toy Story ride, the California Screamin' rollercoaster, a Little Mermaid adventure and the ferris wheel, snacking on churros, cotton candy and corn on the cob. "She fed him," the onlooker says.

Currently shooting The Place Beyond the Pines together, the stars "have been friends for a long time," a source explains to Us. "There's always been this strong chemistry between them...this was just a matter of time!"

Gosling's exes include former fiancee Rachel McAdams plus Sandra Bullock and Kirsten Dunst. (He and Olivia Wilde had a flirty zoo date in Atlanta earlier this year.)

Mendes quietly ended her long-term relationship with producer George Gargurevich over the summer.

"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 adds. "She's never been shy about having the hots for him!"
