Never one to keep her outings private, reality star Khloe uploaded a string of photos to Instagram showing her glamorous night out.
In one photo, she can be seen directing a kiss at musician Fat Joe, while Jennifer stands to the other side smiling at the camera.
"Bronx Kiddddd," wrote Khloe.
Khloe met J.Lo after the star's homecoming concert in the Bronx, New York last night, as Khloe's beau Montana was there to perform with Jenny From The Block.
A source told Us Weekly that Khloe was proudly watching her man perform from side of stage, and later held his hand as he made his way backstage.
Another insider told Hollywood Life: "She looked so proud. She was all smiles while he performed and just danced along to his music."
As well as cuddling up to J.Lo and Fat Joe, Khloe shared a bunch of other pictures of herself, French Montana and fans.
Khloe jetted to New York this week to begin work on her latest E! reality show, Kourtney & Khloe Take The Hamptons! It will follow her and sister Kourtney Kardashian as they launch their Dash Boutique as a pop-up store in the exclusive New York area.
Judging by last night's photos, however, it's not a case of all work and no fun!
Cameo appearances will be made by newlywed sister Kim, who will join her siblings at their multi-million dollar, rented, waterside mansion this summer.
