The Kardashian clan is back at work promoting their lucrative family brand - with Kim Kardashian leading the way once again.

After several months spent in hiding as she worked on losing 50 pounds of gained pregnancy weight, Kardashian, 33, donned a strappy black gown for a new photo shoot with her family.

The cleavage-hugging number showed off her slimmer frame and featured a thigh high slit showing off her legs.

The 'Keeping Up with the Kardashians' stars - including sisters Khloe Kardashian, Kendall Jenner, Kylie Jenner and mom Kris Jenner - posed in extravagant gowns for a beach photo shoot. The only sister missing from the girls' photo shoot appeared to be Kourtney Kardashian.

Khloe Kardashian, 29, also looked to be in good spirits as she joined her family for the beach-side shoot, after a rough couple of months dealing with her rocky marriage to Lamar Odom and the revelation of his supposed drug addiction.

Of course the Kardashian matriarch, 59, was on hand in a billowing burgundy gown, posing happily among her stunning daughters.

Kendall Jenner - who turned 18 on Sunday - looked effortlessly chic in a vintage Alexander McQueen white gown, which she later showed off in a snapshot posted to Instagram.

She and younger sister Kylie Jenner posted a few photos from the day's work, including one on the 16-year-old Kylie's page that turned a few heads.

Kylie Jenner wore a sexy white mini dress before changing into the more elegant gown, and looked way more mature than her age would suggest.
