Gisele Bündchen's day started out rough -- a cop pulled her over in Florida, and she seemed pretty upset over it all ... especially when he handed her a ticket.
Check out this video ... you see a Surfside PD officer pulling over a Mercedes G-Wagon, and not just any G-Wagon ... but Gisele's, one that she's been spotted driving a lot recently. Anyway, you can eventually see Gisele inside ... and she looked awfully emotional.
While it seems like a routine traffic stop .
