It's here! Fashion plate Kim Kardashian premiered her first single "Jam (Turn It Up)" this morning on Ryan Seacrest's radio show, and the tune is available on

(If you're having trouble with the video above, you can also find it on Too Fab.)

Kourtney Kardashian accompanied her sister to Seacrest's studio for the world premiere.
