Uh-oh. Contrary to what Pharell William's single "Happy" is making people feel (which is happiness actually), this ELLE cover of the singer is creating controversy and much unhappiness to plenty of people.

The hashtag #NOTHappy has been making rounds and has made waves around the netizens over what the cover implied. Some of them voiced their negative opinions:

"When will people learn that appropriating native cultural symbols isn't ok?" wrote commenter Jenny Byrd. "Headdresses aren't just hats to be worn by anyone who takes a liking to it."

Carl Chaboyer agreed, writing, "#NOTHappy This is an insulting and ignorant display of cultural appropriation. That's my culture, not a hat." And Johnnie Rae said, "Never looked so good!??? You mean ELLE and Pharrell has never looked so blatantly ignorant."

And another one in Pharell's Facebook page:

Gail Lichtsinn, said: "You have no right to wear a headdress that is so sacred to native people..Those headdresses are earned and not worn to make a buck or draw attention..They have meaning and are worn by our men with pride and dignity..This is a mockery of a proud people..We are not a joke and take these things very seriously..Go back to wearing your OWN clothes."
