They wanna be a part of it…

Reality TV's most famous sisters — two of them, anyway — will star in a brand-new series set in the Big Apple next year.

Starring the two eldest Kardashian sisters, Kourtney and Kim Take New York will debut on E! in January 2011, E! Online confirmed Monday. (The sisters have starred together with their fam in five seasons of Keeping With Up With the Kardashians; Kourtney and little sis Khloe, 26, have appeared for two seasons in Kourtney and Khloe Take Miami.)

Just a few hours before that announcement, a decked-out Kim, 29, and Kourtney, 30, were snapped walking NYC's famous streets.

"Mason, Kim, Scott and I arrived in NYC," Kourtney blogged Monday. "So excited for some fall in the Big Apple. No place better."

(She and beau Scott Disick have a son, Mason, 10 months.)
