Miley Cyrus is calling Urban Outfitters out on Twitter after they were accused of stealing artist Stevie Kourner's necklace design.

"Love that everybody is hating on Urban Outfitters. Not only do they steal from artists but every time you give them money, you help finance a campaign against gay equality," she tweeted with the hashtag 'SHADYASHELL.'

Kourner, who sells her World/United States of Love necklaces that are designed in the shape of states, is accusing Urban Outfitters of stealing her design to sell -- and she shows pictures of their necklaces and her designs to prove it.

"I'm very disappointed in Urban Outfitters. I know they have stolen designs from plenty of other artists. I understand that they are a business, but it's not cool to completely rip off an independent designer's work," artist Kourner wrote on her blog, showing pictures of Urban Outfitters' necklaces and her original designs. "My heart sank a little bit. The World/United States of Love line that I created is one of the reasons that I was able to quit my full-time job. They even stole the item name as well as some of my copy."

It sounds like Kourner has one celebrity supporter for her cause! Miley also goes after Urban Outfitters' CEO Richard Hayne for supporting Pennsylvania senator Rick Santorum, who has spoken out against gay equality.

"'IF WE ALLOW GAY MARRIAGE NEXT THING U KNOW PEOPLE WILL BE MARRYING GOLD FISH' - Rick Santorum UO contributed $13,000 to this man's campaign," Cyrus tweeted.

Urban Outfitters has not yet responded to these allegations.
