The singer was seen leaving the Lyon restaurant in the West Village on Monday evening (12 August) dressed in a very cute fuzzy jumper and leather skater skirt.
She added to her skater girl look with black ankle boots and a tiny backpack.
Katy had been out with BFF Rihanna earlier in the evening, with the pair sharing a sweet picture of themselves having fun via Twitter.
It was the end of a long day for Katy, who released the quirky lyric video to new track 'Roar' that morning and arrived in Times Square later for a publicity event.
Katy has been promoting her new album Prism using a huge gold truck emblazoned with the record's title. It has been driving around the US building up momentum ahead of the album's release.
A drunk driver is said to have collided with the truck while it was stopped at a grocery store in Pennsylvania on 9 August. Damage was caused but thankfully no injuries.
It seems, however, the truck is now fixed and back on the road, as it transported Katy to NYC for her publicity duties yesterday.
Prism is released on 22 October.
