Lorde 'Live on Letterman' (full webcast)
Last night (November 13), New Zealand pop sensation Lorde performed on the Late Show with David Letterman. Not only that, she did a longer non-televised set for the webcast Live on Letterman.

During the TV broadcast, the wild-haired 17-year-old was backed by a couple of musicians as she played her new single "Teams" and danced while decked out in all black. She performed some more material from this year's Pure Heroine during the 27-minute Live on Letterman special, including standouts like "Tennis Court" the world-conquering "Royals."

Watch both clips below.
