The Trying to keep Up With The Kardashians star was in Sin City on Saturday evening (02Jul16), and was witnessed arriving with Trey to Drai's Nighclub at The Cromwell, exactly where the singer is a resident artist. In accordance to Entertainment Tonight, Khloe sat in a VIP booth subsequent to the stage, and watched the Say Aah singer entertain fellow clubgoers with some of his most significant hits. An insider tells ET that later on the two went to Drai's After Hrs nightclub, in which they were spotted creating out early Sunday morning (03Jul16), and "weren't shy" about locking lips with men and women all around them. This is the 2nd time in a week Khloe and Trey were spotted together - final Monday (27Jun16), Trey was 1 of the visitors at her 32nd birthday bash in Hollywood. The two have been photographed leaving Dave and Buster's arcade collectively soon after her celebration, as she playfully touched him on their way out. However, Khloe took to Twitter the subsequent day (28Jun16) to slam tabloid rumours about her really like lifestyle, without explicitly referring to the snaps of her and Trey. "The most irritating point about tabloid rumours is the double standard," she wrote in a given that-deleted submit. "If I am 'spotted' hanging with a guy at a celebration - even if I'm just saying hi for a quick second - it immediately turns into a damaging headline about how many guys I'm dating or how I am receiving back into a new romantic relationship. Men don't get that reputation! They get a pat on the back. It irritates me." Khloe is in the middle of a divorce from estranged husband Lamar Odom. Since splitting from the former professional basketball player in 2013, she has dated rapper French Montana and basketball star James Harden.
