10 times Joshua Jackson was a stylish gentleman

From his well-tailored suits and casual-chic weekend wear to holding doors open for his longtime love, Diane Kruger, Joshua Jackson is always one dapper gentleman. The Canadian actor, who celebrates his 37th birthday on June 11, rarely makes a faux pas in the style department, a skill that he credits Diane for keeping in check.

“I never leave the house in the shambles I used to. [Diane] puts me on the right path if I’m dressing myself poorly,” he admitted to Vanity Fair.

Joshua and Diane are one of Hollywood’s best-dressed (and most adorable!) couples. The German former model is a style icon and highly regarded by top designers like Jason Wu and good friend Karl Lagerfeld, and the Chanel designer’s affinity for Diane has extended to her beau. “Karl bizarrely loves Josh. Before he asks how I am, he would ask how Josh is!”

He's won the approval of the fashion elite (not to mention a spot onHello! Canada's Best-Dressed list) by mastering the not-too-preppy but ready-for-a-weekend-in-the-Hamptons look, almost always topped off with a sophisticated chapeau.

When he’s not winning style points, the star of The Affair likes to set hearts a flutter by publicly declaring his feelings for his girlfriend of nine years and never shying away from taking care of his lady love, both on and off the red carpet. He is often pictured holding an umbrella over Diane’s head while she poses at premieres, helping her down the stairs and pushing the cart at the grocery store - and Joshua’s chivalrous ways don’t go unnoticed.

When asked about his approach to women by Elle magazine in 2014, Joshua said, “It's not the patronizing, patriarchal version where women aren't competent and capable,” he says, adding, “but maybe I just inherited my mother's version of feminism. But to me you can be simultaneously kind and chivalrous without being patronizing. I feel like there's a degree of grace with which you can live your life when it comes to the opposite sex and you should.” (Sigh)
