Sorry, ladies -- Ryan Gosling couldn't be more in love with his longtime girlfriend, actress Eva Mendes.
Gosling, 35, and Mendes, 41, have been dating since 2011, after meeting on the set of their 2012 film, The Place Beyond the Pines. In a new interview with Hello! magazine, the heartthrob makes his feelings for Mendes crystal clear.
"I know that I'm with the person I'm supposed to be with," Gosling says, adding that the only quality he looks for in a woman is "that she's Eva Mendes."
"There's nothing else I'm looking for," he insists.
"This will be our first Christmas where [Esmeralda is] sort of taking it all in, so that's exciting," he shares.
Gosling has also shown his protective side over Mendes. In March, the notoriously private actor took to Twitter to defend the stylish actress after some took offense to her comments that sweatpants are the "number one cause of divorce."
"Obviously sweatpants thing was a joke," he explained. "Wearing them now. That's right, tweeting in sweatpants. Rats! Said too much! You win again Twitter."
Despite being one of the most popular couples in Hollywood, the two have managed to hang on to their privacy and low-key reputation. In September, they celebrated Esmeralda's daughter's first birthday at their Los Angeles home, surrounded by only family and close friends.
"It was a pretty quiet family affair," an eyewitness exclusively told ET about the celeb-free event. "There was no music or any sign of other babies or older kids."
Over the weekend, Mendes supported Gosling following his big Saturday Night Live hosting gig, when she was spotted going to the afterparty with him. The actor reportedly spent a lot of time at the star-studded bash with his old childhood pal, Justin Timberlake, who was also snapped entering the party.
