'Hangovers are the worst!': Khloe Kardashian fails to crack a smile during flight to Dubai after partying in Las Vegas 

She has been on a health kick in the past year with frequent visit to Gunnar Peterson's workout studio in Beverly Hills and lean meals.

But Khloe Kardashian clearly overindulged on Friday night when she hosted a 1OAK party in Las Vegas wearing a semi-sheer black dress.

The next day the 30-year-old reality star hung her head low in an Instagram post. 'Hangovers are the worst,' the Keeping Up With The Kardashians star captioned the image.

The looker had on an oversized yellow hat with a white and yellow band over her blonde locks.

On the E! queen's face was a large pair of dark aviator sunglasses, most likely from the Kardashian Kollection.

And she wore a bronze raincoat with big black buttons. Her white manicure could also be seen.

The daughter of Kris Jenner looked to be on an airplane as she was headed to the Middle East. On Monday she will be a part of a beauty seminar with Fouz Al Fahad at the Dubai World Trade Center,

The rest of her caption read, 'Ugh my head..... this flight to Dubai will be utilized well with this long ass nap I'm about to take I look rough lol.'

On Friday Khloe dazzled in a figure-hugging dress as she arrived at 1OAK, where she played host at a Memorial Day weekend celebration.

With a fitted detail the outfit accentuated her famously voluptuous frame during a brief photo-call with twins Malika and Khadijah Hagg before making her way inside. 

Keeping her locks brushed back she revealed a face heavy on foundation and rich pink lipstick as she beamed at onlookers ahead of her latest night out in the Nevada city. 

Khloe, thought to be single following her split with rapper French Montana, prompted rumours of a fresh romance when she was spotted leaving a late night dinner with Rick Fox at Casa Vega in Sherman Oaks in the early hours of Friday morning 

It was clear that the TV star wanted to avoid being seen with the retired sports star, as they exited the Mexican restaurant separately, apparently at around 1.30am.

Kick back in Khloe's Louboutin heels

We kan always kount on a Kardashian to kill it when it komes to shoes. And Koko is one of our favorite K's, because she speaks to us both literally (on the show) and fashionably (on the red carpet).

And boy did she cut a demure silhouette in her black cocktail dress paired with a simple pair of black toed Louboutins, which are sadly now sold out.

Sometimes footwear dosn't need to make a grandiose statement. Such is the case with Khloe's dainty Louboutin's which practically "disappear"-- allowing for her dress to stand out and make a bigger statement.

Like the fabled "LBD," almost equally as important for every woman to have in her closet are a pair of effortless and uncomplicated black pumps. They're a staple. They're a staple and because they've proven to be so versatile, it probably makes sense to splurge a little on a pair you actually love.

But if you're on a budg, don't worry! Check out our edit below of more addordable options.

Rick was previously in a four and a half year relationship with 34-year-old Eliza Dushku, which ended in April 2014, and was married to Vanessa Williams, 52, for five years, divorcing in 2004.

The NBA star has two children – 15-year-old daughter Sasha with Vanessa, and 20-year-old son Kyle from his relationship with college girlfriend Kari Hillsman. 

On Thursday night, Khloe posted a cryptic quote on her Instagram page, which read: ‘In French, you don’t really say “I miss you.” You say “tu me manques,” which is closer to “you are missing from me.”

‘I love that. “You are missing from me.” You are a part of me, you are essential to my being. You are like a limb, or an organ, or blood. I cannot function without you.’

After four years of marriage, Khloe filed for divorce from Lamar in December 2013, amid allegations of drug abuse and after he admitted to cheating on her. The divorce is yet to be finalised.

In an episode of Keeping Up With The Kardashians which aired in November, Khloe could be seen telling her mother Kris Jenner: 'If I had my way I would still be married to Lamar'.

TMZ claimed last month that the couple have not moved forward with divorce proceedings because they allegedly are not ready to officially end their marriage.
