The singer posted a photo on his Instagram showing off his new buddy at the Seattle Seahawks game over the weekend.
The Seattle native captioned the candid snapshot, "Locker room at the Seahawks game with my step dad Will Ferrell."
How's that for a casual name drop?!
The funnyman posed in another picture with a few other gentlemen and seemed to fit into his new group of pals seamlessly.
It seems as though neither Ferrell nor Macklemore are new to Seahawk fandom.
Both guys have been die-hard fans of the NFL team for years and regularly attend games whenever possible.
Ferrell is quite a sports spectator in general actually. He was most recently spotted at a Los Angeles Lakers game with his son Mattias.
The two had a father-son day courtside and watched their team play against the Denver Nuggets.
But in typical Ferrell form, the proud papa planted a massive smooch on his son's head during the Kiss Cam.
Dads can be so embarrassing!
