Probably the most visible celebrity ‘12’ is Seattle-based rapper Macklemore, often spotted at CenturyLink and/or taking selfies with Russell Wilson.

Wilson, a.k.a. ‘Dwight Schrute’ from NBC’s The Office, is a born & bred Seahawks fan who can be spotted at CenturyLink quite frequently these days (as he was in this tweet from former Seahawk Steve Hutchinson).

Sir Patrick Stewart
Even if Sir Patrick donned a Seahawks jersey for last Super Bowl as a social media stunt, so what? He’s proudly sporting the colors, and it’s cool having him support YOUR team rather than someone else’s. (Photo - Twitter.com/SirPatStew)
Chris Pratt & Anna Farris
One of 2014’s breakout stars, actor Chris Pratt (who grew up in Lake Stevens, Washington) finds time in between shooting blockbusters (Moneyball, Guardians of the Galaxy) to devote to his diehard Seahawk fandom – with his wife, actress Anna Farris and their young child.

Back in September, Ariana Grande - one of the biggest pop stars in the music industry at the moment - took the stage at CenturyLink clad in Seahawks garb for the National Anthem. Afterwards, she even corrected the team's lyrical mistake on Twitter!

Jerry Cantrell & Duff McKagan
Mike McCready isn’t the only 1990s’ rocker proud to be a ‘12’ – both Jerry Cantrell (of Alice in Chains) and Duff McKagan (of Guns n’ Roses, among other acts) are pretty high-profile fans seen around CenturyLink.

There’s no denying that Bill Gates, Microsoft CEO, co-founder (along with Seahawks owner Paul Allen) and all-around ridiculously famous & successful guy, is a devoted supporter of his hometown ‘Hawks. (Photo: Twitter.com/BillGates)
Caviezel, known for roles such as De La Salle High School coach Bob Ladoceur in When the Game Stands Tall & Jesus Christ in The Passion of the Christ, is such a big Seahawks fan that the team’s official site spoke with him about his fandom.
Community star/comedian Joel McHale is among the most vocal celebrity Seahawks fans around, having grown up in Seattle (he went to Mercer High School). He went to Super Bowl XLVIII, too!
Last playoffs, singer Justin Timberlake led a Key Arena crowd in a rousing pro-Seahawks chant – and he’d likely do the same this year if he had a show in the area during this season's playoff run.
