The reality TV star made a whirlwind trip to Sin City with older sister Kourtney on Wednesday (18 September) to promote their Kardashian Kollection clothing line and of course the siblings made sure to travel in style.
Boarding a private jet for their journey, Kourtney and Khloe looked every inch the glamorous A-listers they've become over the years, as they ditched their comfortable airport gear for smart and figure hugging ensembles.
Khloe, 29, could be seen in one picture wearing a khaki green bodycon dress and stilettos, while in another snap (assumed to be taken on their way back from Vegas) she is sporting some skinny jeans, a cute jacket and a pair of Timberland boots.
She captioned the second photo: "5 hour trip to Sin City for @kardashiankollection back to LaLa Land".
Meanwhile, 34-year-old Kourtney looked extra chic in pieces from the sisters' Kardashian Kollection.
She wore a black leather pencil skirt, a flirty tiger print blouse and Tom Ford heels.
The girls' trip comes amid a tough time for Khloe, whose marriage has been put under the spotlight because of claims about Lamar's private life. He was recently arrested on suspicion of DUI in California and reports emerged earlier this month he'd voluntarily checked himself into rehab - although other sources denied this.
Most recently, rumours have emerged claiming that Khloe and the basketball star are now living separately.
According to People, the curvaceous Kardashian is staying with mum Kris Jenner while Lamar has been living at his own place in downtown LA.
A source said: "They're separated for the moment..."
Khloe has remained tight-lipped on the status of her marriage so far, but has hinted she could be in pain via ambiguous quotes and messages on Twitter and Instagram.
Yesterday, she posted a picture of a girl wearing a mask. The words on the photo read: "She smiles to mask the pain in her heart. She laughs to conceal the tears in her eyes."
Earlier this month, she also implied that the rumours could be getting the better of her by tweeting: "As much as I wish I were made of steel... I'm not… I'm pretty damn close to it though hehe."
But despite everything that has been going on in her personal life, it's clear to see that she hasn't let it affect her work and is keeping busy!
