As famous for her insane style and rainbow weaves as she is for her hooks and rhymes, Nicki Minaj is turning over a new wig -- er, leaf. The 'Freedom' MC has kicked her wig stylist to the curb, which may be why she's been sporting sleeker, more subdued styles as of late.

Celebuzz reports that her longtime wig man, Terrence Davidson, has bowed out of working with the sometimes temperamental starlet. “Terrence Davidson most recently served as the celebrity hairstylist, wig creator and creative director for Nicki Minaj,” a press release stated. “After creative differences, he has decided to pursue other opportunities.”

Davidson released his own statement, writing, "It has been an amazing experience offering me a chance to express my creativity and exhibit my love for the art form of wig design. I have decided to part ways from Nicki Minaj because I would like to explore other opportunities within my own brand and re-energize my creativity through work in fashion editorial, beauty consultations, media personality, 'how-to' lectures and hair show development. I am very proud of the body of work built with Nicki Minaj and I appreciate the support over the years from fans who've expressed love for my craft. Look forward to seeing me larger than life in 2013.”

However, a source says that there was more behind Davidson's resignation that just a desire to give lectures on wig making, claiming that Minaj unleashed a torrent of "derogatory statements" against the stylist. No details were given as to what those statements are, but they had to have been pretty bad for him walk away from one of the biggest stars on the planet ... if it's true.

In the meantime, we'll just have to watch Minaj snatch Mariah Carey's wigs on the 'American Idol' set.
