Scott Disick and French Montana now have more than the Kardashians in common ... rap.

We're told a crew went to Scott's Beverly Hills home Wednesday night and set up for French's music video shoot. Scott not only allowed his home to be the backdrop, he became one of the stars. 

The song, "Off the Rip," a remix featuring French and Chinx also showcases Scott's rapping talents. 

People who were there tell us Scott's actually good ... one source says "really good."

French and Scott are comrades, with Khloe and Kourtney under their respective belts and now musical icons.
