Lorde's Royals could be crowned with Grammy gold.
The breakthrough singer will perform at the Grammy Awards nominations special on Friday (Saturday, NZ time) in Los Angeles.
"This will be the greatest number of people to see her in one place at one time," show producer Ken Ehrlich said.
The 17-year-old New Zealand native released her debut, Pure Heroine, on September 30 - the final day to be considered for Grammy nominations. Royals has held the top spot on Billboard's Hot 100 chart for nine weeks.
If she was nominated it would create potential headaches for Laneways organisers. The Grammy ceremony clashes with her scheduled performance at the festival in Auckland on January 27.

Robin Thicke will be joined by T.I. and members of Earth, Wind & Fire for Blurred Lines, the year's longest running No. 1 hit. Keith Urban will take the stage with R&B singer Miguel to sing Bill Withers' Ain't No Sunshine.
"This is really Keith Urban's idea," Ehrlich said, who added that the country star was impressed with Miguel's performance at this year's Grammy Awards.
Rapper-actor LL Cool J will host the one-hour special.
The show will also feature pre-taped performances by Taylor Swift and Katy Perry.
