Kylie Jenner Hits the Town in New York City Before Met Gala

Kylie Jenner isn't letting a little thing like motherhood cramp her style, 'cause Saturday night she hit the Big Apple in a big way.

Kylie was leaving The Mercer Hotel decked out in Alexander Wang ... lookin' motorcycle ready.  She's in town for The Met Gala Monday night.

No sign of Stormi or baby daddy Travis Scott.  They were all in Turks and Caicos celebrating Travis' 26th birthday and Stormi's 3 months BD.
