While visiting the Tonight Show with Jay Leno on Friday (June 29), the Amazing Spider-Man star admitted that even he cannot resist the 31-year-old.
"He's just a dreamboat. It's undebatable," Garfield said.
"He's just stunning," he continued. "Not only physically, but in terms of talent - a general sex appeal that he has."
Garfield's girlfriend and Amazing Spider-Man co-star Emma Stone has worked with Gosling on two films, Crazy. Stupid. Love and the forthcoming Gangster Squad.
In April, the actress refused to compare kissing the two actors, insisting they were like "apples and oranges".
"I love all fruit!" she added.
