The sparks appear to be flying this Fourth of July weekend in Las Vegas.

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.

In video posted onto Snapchat, fans could also see Khloe hanging out in the background as Trey talked to the camera with his friends.
