Ryan Gosling & Eva Mendes Go to Griffith Observatory

Ryan Gosling and Eva Mendes hike around the grounds of the Griffith Observatory on Wednesday (September 21) in Los Angeles.

“Eva wasn’t dressed for the dirt road hike and she walked slowly in her sandals,” an observer told People. “Ryan didn’t seem to mind the slower pace and they … both looked very happy.”

Earlier in the month, the 30-year-old actor and 37-year-old actress visited Disneyland together, while taking some time off from their new movie, The Place Beyond the Pines.

“There’s always been a strong chemistry between them,” one source previously told Us Weekly. “This was just a matter of time!”
