Ian Harding (Ezra Fitz) and Julian Morris (Wren Kingston) play two of Rosewood's most suspicious men on Pretty Little Liars — and on the show, both of their characters seem to have a thing for macking on younger girls. Fortunately, these hot guys go for love interests their own age in real life. But what age is that? Well, Ian Harding is 27, and Julian Morris is 31!

Wetpaint Entertainment teamed up with Viggle to find out if Pretty Little Liars fans were up and up on their actor trivia. The majority of Viggle LIVE! responders did know that Julian is the older actor, but a sizable percentage of voters got it wrong — 57 percent thought Julian was older, and 43 thought it was Ian. Julian's adorable face does make him look younger than he is, so we can see why some people got it wrong.
