Playing See Khloe Kardashian and James Harden Partying in Las Vegas Together

While Kourtney Kardashian and Scott Disick called it quits over the Fourth of July weekend, things only heated up for Khloe Kardashian and NBA star James Harden.

The two certainly looked close in Las Vegas over the Fourth of July weekend, further fueling rumors that the 31-year-old reality star is dating the 25-year-old Houston Rockets guard. Khloe and James had dinner together at Red 8 restaurant in the Wynn Hotel on Saturday night, then headed to Drai's nighclub to watch Chris Brown's concert. According to an eyewitness, the pair looked "very happy," and were "very affectionate" with one another.

Khloe hasn't looked this happy in a while, no?

Khloe and James weren't hiding their affection for one another, and continued to dance until the early morning, the eyewitness tells ET. They arrived and left the club together. Earlier in the day, the reported couple was also spotted showing some PDA out in the open in a private cabana at the Encore Beach Club in Las Vegas.

But not everyone is overjoyed about the budding new romance. James' ex, rapper Trina -- who also happened to be in Vegas over the weekend -- tweeted out a not-so-subtle dig on Sunday.

Khloe and James have been sparking dating rumors since last month. James actually showed up to play basketball for Khloe's brother-in-law Kanye West in June, when Kim Kardashian rented out the Staples Center for her husband's 38th birthday.

The Keeping Up With the Kardashians star is of course no stranger to dating an NBA star. She married Lamar Odom in Sept. 2009, before filing for divorce in Dec. 2013.

Speaking of Lamar, as of April, the exes are still legally married. According to court documents, Khloe's divorce case could be dismissed if she doesn’t complete paperwork to finalize her split from the former Los Angeles Lakers player. Watch below:
