Reality TV star Khloé Kardashian and Trey Songz have social media buzzing following holiday weekend hookup rumors surfacing.

According to reports, the alleged overnight couple locked lips last weekend in Las Vegas, Nevada.

As Trey Songz took to the stage at Drai’s Nightclub inside The Cromwell Saturday night, a special someone was on-hand to show her support. Lo and behold, the one and only Khloe Kardashian was inside and enjoying the show from a stageside VIP booth. Shortly after the concert ended a source revealed to E! News that the Keeping Up With the Kardashians star and rapper met up afterwards and “were seen making out” at Drai’s after hours. (E! News)

Last month, Khloé shut down gossip blogs over rumored dating rumors involving her and NFL superstar Odell Beckham Jr.

In late May, dating evidence surfaced on social media and showed them looking coupled up at rap star Drake’s California home.

TMZ Sports obtained pics of the two getting super close at Drake’s pool party in Hidden Hills on Memorial Day … with Khloe droppin’ her big ol’ butt right on top of the NY Giants superstar. The pics were taken around midnight — and our sources inside the party tell us KK and OBJ were “definitely into each other” and “looked like a couple.” (TMZ)
