Nicki Minaj and Her Rotating Hairdos in 'The Other Woman'

Nicki Minaj changes extreme hairdos as frequently as she changes outfits. So when it came to her first major role in “The Other Woman,” she stuck with that M.O.

"I have new hair in every scene," the 31-year-old rapper-actress says in this Yahoo exclusive behind-the-scenes video from the new revenge comedy also starring Cameron Diaz, Leslie Mann, and Kate Upton.

But instead of raiding her wig closet for hot-pink coifs or lime-green locks, Minaj’s movie looks are much less cartoonish for her role as Lydia, the sassy assistant to Diaz’s character who’s quick to dispense dubious advice to her boss.

Minaj’s hairdos evolve in the film, going from different spins on platinum blond, to a darker, amber blond, to jet black. And her wardrobe, while not as costume-y as Minaj’s typical outrageous fare offscreen, is tight, bright, and bold.

The leading women in “The Other Woman” are styled by “Sex and the City” alums Paolo Nieddu and Patricia Field. And each has a distinctive look:
