#FreeTheNipple was an admirable campaign but from twerk-mania to Nicki Minaj, 2014 has been all about the butt. Better luck next year, nipples.
Jumping on the butt train, Jennifer Lopez teamed up with former Paper cover girl, Iggy Azelea for her new -- creatively titled -- track, "Booty." The video treatment for J. Lo's ode to the butt is exactly what you'd expect -- bikinis, lots of weirdly thick oil (possibly J. Lo's youth serum?), and plenty of big booty shaking. Watch the video for "Booty," above.
