Eminem, whose real name is Marshall Mathers, watched the intense matchup from a private suite inside of Levi's Stadium while sporting a Lions T-shirt and a gray cap with the team's logo.
At one point during the game, it seems he became involved in a heated exchange with 49ers fans sitting in seats below his VIP suite, prompting him to respond by giving the group of individuals in red jerseys the double bird, as seen in viral photos shared to social media.
While it seems Eminem's not-so kind gesture occurred when the Lions had the lead, the 49ers ended up winning the game thanks to a 27-point comeback after half time.
After the unexpected photo of Eminem went viral on social media, users couldn't help but share their reactions.
"Full on mood!" one Lions fan wrote in support of "The Real Slim Shady" rapper, while another joked, "this aged horribly" following the 49ers win.
Some viewers of Sunday's final playoff rounds were hoping for an "Eminem vs. Taylor Swift Super Bowl," though only one half of their wishes came true.

"Do we have dad?" Taylor was filmed asking Donna as they made their way to Travis.
Donna appeared to confirm, though Taylor continued to make sure the whole family was accounted for, stating, "We have dad. We have Jason."
Security then offered to escort her via a specific route, however, Taylor said, "I don't know" before deciding, "I'm gonna do what she does," in reference to Donna.
Once she found Travis on the field, Taylor was adorably seen locking lips with him while expressing how proud she was of her handsome man.
At one point, Travis was handed a microphone to address reporters, his team and the crowd of friends and family welcomed onto the field.
"You gotta fight for your right to party!" Travis exclaimed in response to the big win, causing Taylor to giggle as she continued to applaud her boyfriend.
