The most outrageous GRAMMYs looks of all time

All sensible style rules are thrown out the window for the GRAMMYs.

Stars have rocked some jaw-dropping styles through the years -- and you better believe celebs will top those outrageous looks at the big show this year.

Fergie has repeatedly made heads turn on several occasions, including in 2012 when she stepped out in an orange Roberto Cavalli lace number. The bright hue of the gown is very similar to the color of a prison uniform.

Of course, there was Jennifer Lopez's iconic green Versace gown from the 2000 GRAMMYs, which may be the show's most memorable look of all time.

Lady Gaga and Nicki Minaj, two stars who have a flair for the dramatic, have donned bizarre outfits over the years to the point that it's not even surprising anymore. In 2012, Minaj showed up with a strange accessory -- an old man dressed up as a pope. Gaga wore an uncomfortable-looking gown in 2010 that had many wondering: How did she manage to sit in that?!

Check out all the other outrageous GRAMMYs looks through the years in the gallery above, and see all of the looks from last year's show in the gallery below:
