Nicki Minaj & Katy Perry Flaunt Pink Hair At The Grammy Nominations Concert (PHOTOS, POLL)

And we shall know our successful musicians by the hue of their hair?

That seemed to be the lesson at last night's Grammy nominations concert, when Nicki Minaj and Katy Perry showed up with manes that looked practically identical (at least in terms of color).

Both ladies wore their hair in a candy-colored shade of pink. Nicki kept hers flowing in a long pink wig that offset her -- surprisingly simple! -- blue strapless dress, while Katy swept hers up, save for a long piece in the front, in a strapless dress that almost matched her hair perfectly.

They even tied on nominations: Nicki received two noms for Best New Artist and Best Rap Performance (for "Moment 4 Life"), while Katy nabbed two for "Firework" - Song of the Year and Best Pop Solo Performance.

But it's not like the ladies' salmon hair color was shocking: Katy's had pink hair for awhile, and really, has Nicki ever worn the same hair shade twice?

At least we know what we'll be getting these girls for the holidays this year.
