When this star found out she was going to a green event, she really got into the theme with this two-toned wig.
The singer donned this over-the-top coif to celebrate the eco-concious party last night in NYC.
Of course, she's no stranger to wearing crazy hairpieces.
Think you know who's got green roots? Find out after the jump...
It's Nicki Minaj, who was the surprise guest performer at Christie's and Runway to Green present The Bid to Save the Earth event last night.
The evening was hosted by Seth Myers with celebs like Diane Kruger and designer Jason Wu on hand to support eco-friendly fashion.
Diane isn't just going green in her wardrobe...she says she's also made changes at home to help the environment.
"We have solar panels, especially in L.A., that makes sense," she told me, "We make our own carbonated water. We don't ever buy water anymore."
(We assume the "we" she is referring to is her and boyfriend Joshua Jackson.)
Diane also said her Inglourious Basterds costar Brad Pitt really knows his stuff when it comes to going green without spending a ton of green.
"He is very much involved with it," she said, "He obviously didn't study as an architect, but he's really taken such an interest in making houses green and that it doesn't have be more expensive."
We'll live in a house that Brad built anyday...as he long as he lives there as well. Angie is welcome, too!
