What do you do when you just signed the largest contract in the NFL???
If you're Russell Wilson and Ciara ... you make a celebration video from the comfort of your own bed!
The Seahawks quarterback inked a 4-year, $140 MILLION deal late Monday night -- with $65 MILLION guaranteed!!!
The deal makes 30-year-old Wilson the highest paid player in the league ... leaping over guys like Aaron Rodgers, Matt Stafford, Matt Ryan, Kirk Cousins -- even Tom Brady.
