Move over, Santa ... Robby Anderson is now the king of Christmas -- at least this year -- 'cause the Carolina Panthers star surprised his fiancée with a custom, 2021 G-Wagon for the holiday!
The NFL player had the awesome Dreamworks Motorsports ride delivered over the weekend -- and it arrived in style, coming inside of a glass box.
And, check out video of the surprise, Anderson's fiancée, Sade, was so blown away by the present ... she fell to the ground!
