Chris Pratt and Anna Faris came to Phoenix ready to party!

Wearing Seattle Seahawks T-shirts, the spouses of five years were the stars of the dance floor at a Super Bowl bash hosted by Maxim for thousands of revelers at the Scottsdale, Arizona airport.

Laughing, kissing, and singing along to the music – including a surprise performance by rapper/actor (and newlywed!) Lucadris – Pratt and Faris joined celebrity guests including Tom Arnold, Alyssa Milano and Celebrity Apprentice contestant Ian Ziering.

But Pratt also had some business to take care of, talking over his sweet Super Bowl bet with Chris Evans, 33.

If Pratt’s team, the Seattle Seahawks, win Super Bowl XLIX, Captain America star Evans will have to show up at the Seattle Children’s Hospital dressed as the superhero – in a Tom Brady jersey.

If Evans’ New England Patriots win, Pratt will visit Christopher’s Haven, a Boston nonprofit that aids families of young cancer patients, dressed as his Guardians of the Galaxy hero Star-Lord, toting the Seahawks’ fan emblem, the 12th man flag.

Nick Cannon and rapper French Montana popped into the party for a little while, too.
