cara delevingne + a$ap ferg battle it out

in the ultimate walk-off.

Watching Cara Delevingne walk down the runway is always something worth seeing, because she freakin' kills it. Aside from her famous brows and perfect face, the It Girl's walk is something that has propelled her from well-known model status to household name, and beyond. Oh, and when we say "beyond," we mean the subject of a rap freestyle lyric from hip-hop dude A$AP Ferg. In "Dope Walk," a track from the Mob rapper's new mixtape Ferg Forever, A$AP has this to say about Cara:

"My walk meaner than Cara Delevingne's."

Now, when you're Cara f*n Delevingne, you can't just let something like that happen. You've got to show A$AP just how mean your walk actually is, which is exactly what the supermodel just did on Instagram.
