While on their way to Las Vegas after partying together in New York City, Khloé Kardashian and new flame French Montana were reportedly caught having sex in a car outside an airport.

Over the last weekend, the "KUWTK" star was seen enjoying PDA with the "I Ain't Worried About Nothin" hitmaker at a yacht party for her 30th birthday. When the couple arrived to the airport on Wednesday, July 2, to fly to Sin City for another of Kardashian's birthday celebration, they found out that their flight was delayed.

According to MediaTakeOut, an eyewitness claimed that the two headed back to their Mercedes Benz Sprinter van to have a hookup session. "A passerby saw them go inside their Sprinter van... and then saw it rocking back and forth," the website reported.

While the pair's relationship seems to get pretty serious, Kardashian is apparently not ready to have children yet. "She's definitely not trying to have a baby," a source revealed to Hollywood Life.

On Friday, July 4, the reality star and the 29-year-old Moroccan emcee appeared on the red carpet together at Las Vegas nightclub Tao. People reported that they stayed close and intimate with each other throughout the evening at their V.I.P. table off the dance floor, and stopped cuddling briefly only when Kardashian had to cut her birthday cake.

When asked before partying what makes French Montana so special to her, Khloé Kardashian said: "He's just funny, he's light and easy," according to People. "That's what I need right now. He's fun. I like that he's always happy. Smiles are infectious and contagious, so I like that."

As she just turned 30, the only thing she wants is happiness. "I just want positivity and having fun," said Kardashian. "I don't know. I'm only a couple days into it."
