The reality stars were joined by Kourtney's boyfriend Scott Disick and kids Mason, four, and Penelope, one, as they left a Manhattan hotel on Monday (2 June).
Khloe, Kourtney and the gang jetted to New York from Los Angeles this week to begin work on their latest E! spinoff, which will follow them as attempt to launch a Dash pop-up shop in the exclusive Hamptons.
Dash is the Kardashians' fashion and accessory boutique.
Khloe looked chic in jeans and a black top as she held onto little Mason with one hand and kept a chilled drink in the other.
Her outing came after she posted a controversial photo to Instagram showing herself swigging from a champagne bottle while rumoured boyfriend French Montana posed with a toy gun.
Kourtney, meanwhile, was dressed down in skinny jeans and a floral loose shirt as she carried daughter Penelope on her hip. Long-time boyfriend Scott also dressed for the New York heat, looking ready for the beach in his blue shorts and open necked checked shirt.
While plenty of Kardashian fans are eagerly awaiting Khloe and Kourtney's advertures in the Hamptons, reports claim that local residents haven't been as thrilled, citing concerns about traffic chaos and public safety if the filming causes a scene.
Kourtney & Khloe Take The Hamptons! will feature cameo appearances from newlywed sister Kim Kardashian West, who has just returned to to the US from her European honeymoon with husband Kanye West.
It's just the latest in a string of Keeping Up With The Kardashians spinoffs, which have included Kourtney & Kim Take Miami!, Khloe and Lamar, focusing on Khloe's marriage to ex-husband Lamar Odom, and Kim's Fairytale Wedding, which documented Kim's marriage to ex-hubby Kris Humphries.
