Rob Kardashian and Blac Chyna have taken on one of their moments in Las Vegas over the weekend. The couple celebrated Memorial Day in sin city on Saturday.

The couple reportedly got to the Las Vegas' Sky Beach Club at 3 p.m. on Saturday, according to People magazine. When Rob and Chyna arrived, they went over to sit at the club's VIP area, just at the back of the DJ booth. The DJ booth is a place that looks over the club's two pools. These pools are swamped by the two towers situated at the Tropicana Hotel.

Observers have seen the "Keeping Up With The Kardashians" reality actor sipping Moet champagne and apple Ciroc, hanging with about 20 people. Chyna was reportedly wearing a tan dress highlighted a growing belly. Sans the likely pregnancy, Chyna was seen drinking water and eating sliders, onion rings and chicken fingers.

The pair reportedly did not speak to the media. However, the couple was seen taking selfies with their fans. Chyna thanked a fan who complimented her after she and Rob took photos with fans.

Later on, Chyna was seen drinking a non-alcoholic beverage from a disposable plastic Skyy cup. After doing so, Chyna showed the crowd her 7-carat engagement ring.

Meanwhile, Rob and Chyna are allegedly getting a deal to get a pay of about "seven figures" in amount, just for the pair's release of pictures of their offspring that is about to be born, as reported in The New York Daily News.

TMZ reported that for the couple to get their millions of dollars pay, they would need to be included in the photo of their infant son/daughter, when their offspring is born. 

Rob's sister, Kim Kardashian, though, has not received a pay from the media for photos of her children,  as reported in The Daily Mail UK.
