They have been busy little bees as they help keep the Kardashian empire humming.

The rest of the Kardashian/Jenner clan don't appear to be holidaying with the girls and their parents.
Kendall and Kylie's downtime comes after a busy few weeks for the reality stars.
The sisters recently travelled to Sin City for a promotional appearance at Kardashian Khaos, where they posed with the family's merchandise.
The pair are obviously stepping up their work for the family, with Kim busy with commitments around the globe and sister Kourtney heavily pregnant.

Meanwhile today it was revealed that Kim has been linked to a convicted fraudester in a bizarre legal motion.
Jonathan Lee Riches, who has filed more than 2,600 lawsuits since 2006, claims that he made two sex tapes with Kim and lost his virginity to her whilst on a trip to Armenia, according to documents obtained by RadarOnline.
Oddly, the man has submitted the motion asking that he be added as a plaintiff in Kim's lawsuit against The Gap and Old Navy.

Kim is seeking up to $20m in damages by claiming clothing retailer The Gap cashed in on her fame by using lookalike model Melissa Molinaro in an advert for the Old Navy brand.
In the motion Riches claims he has been in a relationship with Kim for over 10 years, and that he and the reality star, who famously made a sex tape with ex-boyfriend Ray J, also appear on camera together.

Riches says: 'Kardashian is now threatening my life since I got released from prison on 4/30/12, telling me if I expose our relationship that she is going to get her sister Khloé's husband, Lamar Odom's basketball buddies to come hunt me down and stuff basketballs in my throat to shut me up.
'Im so scared, Im whistleblowing now, because Kim Kardashian should of went to prison for my crimes, I did it all for her.'
