Ryan Gosling Once Said These 2 Actors Were His "Greatest Girlfriends of All Time"

Gosling reportedly dated Bullock for almost a year after meeting her on the set of their 2002 movie "Murder by Numbers." He was just 22 years old at the time, while Bullock was 38. The pair kept their relationship under wraps until they split for unknown reasons in 2003.

The "Notebook" costars met on the set of their romantic drama in 2002, but apparently, it was far from love at first sight. According to a 2014 interview with VH1, director Nick Cassavetes claimed that Gosling and McAdams did not get along while filming their classic movie. Nevertheless, the couple spent three years together before calling it quits in 2007. Despite the breakup, Gosling still valued his relationship with McAdams. In 2011, he told The Times he "had two of the greatest girlfriends of all time," in reference to McAdams and Bullock, per Us Weekly. "I haven't met anybody who could top them."

Although Dennings refused to admit in a September 2009 MTV interview that she and Gosling were once a thing, the two were spotted having a date at Disneyland just a month before when rumours began to swirl. "I can't talk about my personal life," she told the outlet without confirming or denying her relationship with Gosling. To this day, their alleged romance has never been confirmed.

In 2010, there were rumours that Gosling and Lively had eyes for each other, but nothing was ever confirmed besides reports that the two of them went on an ice cream date to — you guessed it — Disneyland.

According to HuffPost, Wilde and Gosling attempted to have a low-key aquarium date in 2011, but their disguises weren't enough to fool fans who spotted them together. The two were also seen cosying up together at an Oscars afterparty that same year, but their rumoured romance was never officially confirmed.

Gosling and Mendes first met on the set of the 2011 film "The Place Beyond the Pines." While courting her, Gosling also took Mendes on a date to Disneyland, and the rest is now history. Since then, the private couple have welcomed two daughters and quietly kept their romance going for more than a decade now.
