Ryan Gosling Goes Back to Work; Makes a '70s Moustache Hot

Ryan Gosling is back, and looking better than ever.
In his first appearance since welcoming daughter Esmerelda Amada with girlfriend Eva Mendes on Sept. 12, the 33-year-old actor was spotted on the Atlanta set of his film The Nice Guys. And that's quite the killer 'stache. He even manages to make his '70s outfit -- blue pants, a printed button-up shirt and a brown tie -- look hot.
Also co-starring Matt Bomer, Russell Crowe and Kim Basinger, The Nice Guys revolves around a private eye (Gosling) who investigates the apparent suicide of a fading porn star in 1970s Los Angeles and uncovers a conspiracy.
The film isn't out until June 17, 2016.
"They shot during the day and at night," a source tells E! News about the new dad's first day on set. "Ryan was in good spirits, but seemed tired."
Gosling and Mendes, 40, have unsurprisingly continued to remain extremely private about their new baby girl, though a look at their newborn's birth certificate revealed her super-unique Disney-themed name.
