For all the intriguing hairdos Nicki Minaj regularly sports in music videos or otherwise, the rapper is facing legal troubles.

A celebrity hair stylist is seeking $30 million from Nicki Minaj, claiming the rapper stole his designs for the colourful wigs that have become synonymous with the former American Idol judge.

Terrence Davidson filed the lawsuit in federal court on Friday in what his representatives claim is the first-ever intellectual property dispute over wigs in recorded American history.

`She lied, cheated, she stole from him,` Christopher Chestnut, an attorney for Davidson, told The Associated Press. `That's a misappropriation of his intellectual property.`

Davidson, 41, first began working for Minaj in 2010, but stopped working for the singer more than a year ago.
