If you're a fan of the television show 'This Is Us,' then you're well aware of the role of Kevin Pearson, played by actor Justin Hartley, of the Pearson family, who the show is built around along with this two siblings and parents.

With the finale of season three set to air on April 2nd, Hartley is currently filming a movie in the Ottawa region.

The Illinois native grew up a Blackhawks fan and was a guest of the Senators on Monday night during their game against the Tampa Bay Lightning.

During the first period, Hartley joined TSN's Brent Wallace for an interview and explained how he became such a fan of puck, and even provided a bit of a spoiler for fans of the popular T.V. show.

What a spoiler, eh? It's cool to see Hartley respect the game so much given the contemporary appeal of speed and skill.

It also doesn't hurt that his friend's dad is one of the most popular sports broadcasters, either.

You can watch the season finale at 9pm ET on CTV.
