Everyone wants to be Ryan Reynolds, even <i>This Is Us star</i> Justin Hartley! The actor appeared on <i>The Tonight Show Starring Jimmy Fallon</i> on November 21 where he recalled a hilarious fan encounter that left him pretending to be the Canadian actor. 

It all started when he bumped into a “fan” at a charity event. “It’s really neat because you get to raise money for good causes, and people recognize you, and they’re really nice to you,” he said. “This woman recognized me, and I could tell she did because she made this face."

As he showed a shocked expression, the 40-year-old added: “She really likes me! I was feeling pretty good about myself. She starts telling me how great I am and how in love with me she is… She asked how Blake was, and I didn’t know what she was talking about. She then asked me if I knew <i>Deadpool</i> was going to be that big of a hit.”

The handsome actor didn’t have the heart to tell her the truth. “I just pretended like I was the coolest guy on Earth,” he said with a laugh.
