Splash News

Blac Chyna and Rob Kardashian are enjoying the Miami, Florida nightlife before they add a newborn to the mix.

For the model's 28th birthday, the newly engaged couple celebrated in the VIP section of the G5IVE Gentleman's Club. Rob -- who was wearing his usual all-black outfit -- didn't venture too far from his fiancee, who had that pregnancy glow. The birthday girl wore a tight white jumpsuit, but she wasn't showing much of a baby bump just yet.

Prior to their club appearance, Rob arranged an intimate dinner for Chyna and four of their friends at Katsuya at the SLS South Beach hotel. "The couple seemed completely in love, and stole kisses throughout the dinner," a restaurant patron told ET.

The couple were anything but incognito at the eatery. When Chyna's birthday dessert was brought to the table, the group loudly sang "Happy Birthday" and clinked glasses of prosecco while she blew out her candles. From there, the group took a moment to lounge poolside at the hotel before heading to the gentleman's club.

Rob and Chyna's Miami getaway comes after the 29-year-old reality star surprised his future baby's mama with a room full of flowers. He also gave her a cake that looked like a floral bouquet. "Twenty-eight bouquets of flowers with 28 reasons why I Love Her for her 28th Bday‼️" Rob Instagrammed. "HAPPY BIRTHDAY ANGELA!! Awwwww I'm the best‼️ I LOVE YOU!!"

In addition to her birthday, Chyna also celebrated the success of her Chymoji app that topped the charts on Wednesday. "OMG ! I wanna Thank everyone that made Chymoji," she wrote. "No. 1 @chymojii #chymoji."

Chyna and Rob also attended the Chymoji launch party on Tuesday night at the Hard Rock Cafe on Hollywood Blvd. "I'm so excited to finally be apart of the technology world! This is a significant step in my future of business ventures,” Chyna said at the event. "There's so much that I have in the works as far as my career is concerned. I'm just grateful that God has allowed these opportunities to find me."

Meanwhile, some fans are speculating that a few of the Chymojis hint that the couple are expecting a boy. One of the emojis in question is of Chyna holding a baby that is peeing in the air next to Rob. There's also an image of a blue bottle, which could be blue for boy.
