Wheeeee! Emma Stone has been going all out to celebrate boyfriend Andrew Garfield's 29th birthday.

The couple, who have been dating for nine months, let loose at Disneyland in Anaheim, Calif. on Thursday. Stone, 23, and the birthday boy screamed their way down the Splash Mountain log flume ride, which was captured in a funny photo with two other pals. Sitting in front of a yelping Garfield, the actress had a huge smile on her face as she held on tight.

In more photos on Buzzfeed, the Spider-Man costars also enjoyed competing against each other in Buzz Lightyears Astro Blasters ride, and even styled some silly Disney hats while walking around the park.

On Garfield's actual birthday, Monday, the twosome enjoyed a little PDA on the beach in Malibu, Calif. Stone profanely honored her beau's special day by wearing a white t-shirt with "Happy F---king Birthday" written in on the front.

For British actor Andrew, it was love at first sight working with Stone on The Amazing Spider-Man. "We got on really well as people, in between [takes]. That was the fun stuff: In between, we'd just mess around and I felt, 'Ah, this is different.' I wasn't really aware of what was happening in the screen test," Garfield told MTV News. "She keeps you on your toes and that wakes you up. That was the beginning."
