Hey girl, sometimes dreams do come true. Last fall, officials at the Texas School for the Deaf in Austin hoped to entice Ryan Gosling to attend a charity fund-raiser by posting an open invitation in the form of the flirty "hey girl" Internet meme that riffs on his don't-you-wish-he-was-your-hipster-boyfriend reputation. The day of the event, Gosling shocked organizers by turning up-with Rooney Mara and Michael Fassbender, his costars in the untitled Terrence Malick film shooting in town. Gosling happily mingled, took photos with a long line of excited parents and kids, and at one point, "he paid $50 for a $1 glow-in-the-dark cotton candy," says Anne Adams, executive director of the school's foundation. "He insisted on learning the sign for please and thank you so he could properly show his appreciation to the child. He deserves every one of those 'hey girls!'"

And so the perennial Sexiest Man Alive-in-Waiting (hmm, someone should get on that) continues to perfect the art of Being Ryan Gosling. In the past year, the 32-year-old actor cheered on his mom at her college graduation, doted on his dog George and homeless pups at an Austin pet rescue group, honed his blogworthy biceps via Muay Thai kickboxing, and worked on four films, including the new thriller Gangster Squad. But the guy who makes both double-breasted suits and tank tops look cool still struggles to wear the sex-symbol thing lightly. "You just try not to think about it, and you take advantage of the fact that you have these opportunities that you can control-who you work with and what you make," Gosling told PEOPLE at the Jan. 7 Gangster Squad premiere in L.A. "You try and do the best [you can] with that freedom."

In addition to many, many pairs of skinny jeans, the year also brought some bumps in the road for his romance with actress Eva Mendes, 37, whom he fell for in late 2011 while filming The Place Beyond the Pines. They broke up last March, only to reunite in May. But they haven't been spotted together since Nov. 26, sparking heated fan speculation-wishful thinking?-that he might be back on the market. Sorry, but the two are still going strong-so much so that Gosling's mom, Donna, boasted of raiding Mendes's closet for her premiere outfit. "The nice thing about their relationship is they don't put so much pressure on it," says a source who knows both stars. "It doesn't feel overly complicated." Adds a Gosling source: "Ryan and Eva get along so well because she's not needy or smothering. They just work."

Meanwhile, Gosling continues to dub-step to the beat of his own drummer. Since his breakout role in 2004's The Notebook, the Ontario-bred actor has mostly stuck to indie productions, with Gangster Squad his biggest-budget film yet. A restless kid who was homeschooled by his single mom after starting fights, the former Mickey Mouse Club star has struck a few colleagues as aloof. But others offer raves. "I don't think he's cocky," says stylist Blair Levin. "He's down to earth and super nice." His Gangster Squad director Ruben Fleischer calls him "funny and charming. When you're with him you feel different. He has a magnetic quality-larger than life."

For all his studied quirks-ballet classes! ukelele! Marlon Brando voice!-Gosling has a traditional side when it comes to relationships. The serial monogamist, who gushed that he had "two of the greatest girlfriends of all time" (referring to Rachel McAdams and Sandra Bullock, reportedly), deserves his rep as "an incredibly sweet boyfriend," says a source close to him. "He has such good manners." Though Mendes has said she's not the marrying kind, Gosling "adores kids and can't wait to be a dad," says another source. "He's going to make an amazing father one day." Hey boy, it's decided: You're a dream guy, like it or not.
