Rapper Mike Stud is no dummy ... putting his smokin' hot model GF Josie Canseco front and center (in a thong) in his new music video for his song "Anyone Else" ... and TMZ Sports has the footage.
Stud and Josie -- daughter of the baseball legend -- have been dating for a while ... and Stud wrote the song about her.
You gotta watch the entire thing ... Josie (who's already been featured on SI.com) flaunts her insane physique while eating pizza and a grilled cheese sandwich.
