Nobody was happier to see Aaron Rodgers' insane comeback Sunday night than Danica Patrick ... 'cause she showered her man with praise after the win -- calling him the greatest of all time!!
The ex-NASCAR driver had a luxury box seat to Rodgers' rollercoaster ride against the Bears ... with cameras showing her nervous during Aaron's injury and shock during his comeback.
Danica Patrick can't believe it either. pic.twitter.com/YGPvfA5R19
When the game was over -- and the injured QB had led his team from down 20-0 to a 24-23 win on one healthy leg -- she took to social media.
The pic was of a Lambeau Field T.V. -- complete with a goat emoji and the words, "Unreal baby."
FYI ... this ain't the first time Danica's celebrated her man's Packers greatness -- remember the custom bottle of champagne she popped after he inked his mega deal?!
Seems like Aaron's not the only one angling for a ring this season ...
By the way ... Randall Cobb -- the dude who caught the game-winning, 75-yard touchdown from Rodgers -- had quite the postgame celebration too ... giving his newborn baby the game ball!!
The baby boy -- Caspian Cyrus Cobb -- is barely a month old ... but little man's already got a piece of Packer history for the rest of his life.
Good times in Green Bay.
