Khloe Kardashian had an awkward moment when she accidentally met former boyfriend James Harden while attending a concert in Las Vegas.

The youngest Kardashian sister had a busy trip in Las Vegas where she attended several events including Scott Disick’s birthday celebration. She also managed to meet her ex James at Future’s concert held at Drai’s Nightclub on Friday, May 27. A source has shared with Entertainment Tonight that the former couple’s unexpected reunion was not a happy one.

"The tension was tight, and they were making eyes at each other," the source stated. The meeting between Khloe and James was also “coincidental,” the source explained. It appears that the “Strong Looks Better Naked” author did not spend a lot of time at the said event. After the performance, the “Keeping Up with the Kardashians” star reportedly headed straight to the airport.

Khloe and James first stepped out as a couple in July 2015. However, after several months of dating, the two separated in February 2016.

In a previous episode of the now-cancelled show “Kocktails with Khloe,” the reality star candidly shared some details about her break-up with James. She recounted how the basketball player had sought her out and wanted a relationship with her, as stated in the same report. “He wanted to be committed and, you know, then wasn't committed. So Koko had to go go!" Khloe added.

Meanwhile, Khloe stole the show during Scott’s birthday celebration at 1OAK in Las Vegas, according to InStyle. The TV personality wore a pink latex dress that hugged her curves and showed off her cleavage. Kris Jenner’s daughter partnered the dress with white heels and several jewelry pieces to accessorize the look.

In a recent Instagram post, Khloe also showed off her latex dress. The TV personality uploaded a side-by-side photo of herself wearing the pink figure-hugging dress at the red carpet event at 1OAK. She captioned the image, “When in Vegas wear latex according to @monicarosestyle!! Monie, I love you!”

It appears that Khloe may have went against the stylist’s instructions by wearing white shoes with the pink latex dress. “Sorry I wore white shoes Monica! Lol,” she stated on Instagram.
