Kills, who now goes by 'Teddy Sinclair', celebrated by sharing a hand-written note in Instagram. She recounted touching a Grammy award at a "rich guy's house once" where they did "free coke off a $9000 mid-century Danish peak coffee table".
She also wrote that she was about to "rent that yellow Lamborghini with the fabourge rims".
Kills rose to prominence in 2013 with her song Saturday Night, before landing a role as judge on the second season of the X Factor NZ alongside her husband WIlly Moon.
The two were dramatically fired from the show midway through the season after Kills and Moon abused contenstant Joe Irvine for allegedly copying Moon's style.
The Grammy Awards will be held on February 13. Kills faces competition from songs written for Drake, Bryson Tiller, Maxwell and Tory Lanez.
