Nicki Minaj's green hairstyle

Green with hair envy

Keeping with the spirit of the evening, Tuesday night Nicki Minaj attended the Runway To Green charity event at Christie's, as Vogue's special guest performer.

Apparently, editor-in-chief Anna Wintour was the one who invited her. The charity raised more than $1.2 million in under an hour by live auction alone.

Lots included:

• Oscars getaway to Los Angeles (complete with two tickets to the David Furnish pre-event dinner, two tickets to the Elton john AIDS Foundation Dinner, and two tickets to the Vanity Fair Oscars Party)
• Luxury four-region Alain Ducasse culinary world jaunt (through New York, Paris, Provence, and Italy)
• Seven nights in Paris during Couture Week and two front-row tickets to the Chanel Couture Show

But those weren't even the BIG lots. There were three big celeb packages on the block -- a flight and lunch with Harrison Ford on one of his private aircrafts; the Chanel package, which included a meet-and-greet with Karl Lagerfeld himself; and a day hanging out with President William J. Clinton, which ended up going for $100,000.

Wowzers!
