The Keeping Up With the Kardashians beauty and the Houston Rockets ace were snapped showing public displays of affection during a pool party at the Encore Hotel on Saturday (04Jul15), while they reportedly enjoyed an intimate dinner date that night and then attended a Chris Brown concert together, according to TMZ.com.

Khloe Kardashian, who is estranged from her husband, basketball player Lamar Odom, has yet to comment on the new relationship claims, but the news appears to have irked her former love rival Trina, who has dated both Harden and the reality TV star's other ex, rapper French Montana, in the past.

Trina took to Twitter.com over the weekend and snidely remarked, "Sloppy seconds" - a comment fans have interpreted as a reference to Kardashian's latest conquest.
