Hairstylist Terrence Davidson has sued his former celebrity client, singer Nicki Minaj, in an intellectual property lawsuit over wigs.

Davidson has filed a $30 million federal lawsuit against the entertainer, reports contactmusic.com.

Minaj has reportedly repeatedly stolen his ideas without compensating him for his efforts.

Davidson alleged in his lawsuit that he started working for Minaj at the beginning of 2010. He worked as the wig maker for most of her public appearances, including her 2010 MTV Video Music Awards pre-show.

The hairstylist believes that he has helped create her image and so, he wants to be compensated accordingly.
