The 2012 Grammy Awards was held yesterday and, as expected, there were some celebrities who clearly didn't consult anyone before they decided what to wear.

Nicki Minaj is known for wearing bizarre outfits but yesterday was possibly the strangest she has looked yet. The YMCMB femcee arrived at the ceremony as a woman of the cloth, accompanied by the Pope - well, not the Pope, but a very good lookalike.

The unknown man could not have looked happier to be brought along to the biggest music event of the year as Nicki guided him along the red carpet.

Meanwhile, Fergie wore a totally inappropriate flourescent orange see-through dress, in which her black underwear wear clearly visible.

Rick Ross was also among the worst dressed, for rocking up in a plain stripy t-shirt and jeans. For someone who raps about ballin', you would have thought he would've made more of an effort!

Check out the pics of their horrific outfits in the gallery below. Who do you think looked the worst?
