Rob Kardashian Shows Off Weight-Loss On Vacation To Jamaica With Blac Chyna [PHOTO, VIDEO]

Rob Kardashian and his new girlfriend Blac Chyna jetted off to a tropical vacation in Jamaica over the weekend, and they sure do look like they enjoyed their time on the island. The two mixed business with pleasure as Kardashian joined Chyna for her scheduled club appearance in Montego Bay's BritJam spring break festival on Sunday night.

The two flew first class from Los Angeles International Airport (LAX) on Saturday just days before the "Keeping Up with the Kardashians" star's 29th birthday. Chyna, 27, documented the quick trip to Jamaica on her Snapchat in a series of videos and pictures that showed her and Kardashian in the plane on the way to the island. They arrived at the Sangster International Airport in Jamaica early Sunday morning.

"They both looked happy, but showed no signs of affection," an eyewitness said of the new couple.

This was not the first time Chyna and Kardashian set off for a weekend away full of partying. Last week, Kardashian joined his girlfriend for another club appearance, this time in Georgia where the couple partied together at the Medusa Restaurant and Lounge.

Kardashian and Chyna first revealed their relationship back in January and sent shockwaves through the Kardashian/Jenner family. The model and entrepreneur used to be engaged to Tyga, Kardashian's youngest sister Kylie Jenner's boyfriend. Tyga and Chyna also share a son together, 3-year-old King Cairo. When the news of the relationship between Chyna and Kardashian broke, a source said that his older sister Khloé felt "majorly betrayed by Rob after she always stuck up for him. She feels like this is a major blow to the family. Nobody in the family likes it."

Chyna was previously close friends with Kim Kardashian, but their friendship seemed to fizzle once Tyga started dating Jenner, who was underage at the time.

Earlier this month, rumors swirled that the two had broken up after only dating for about two months when Kardashian deleted all his Instagram posts of his girlfriend, and Chyna tweeted a quote that referenced a breakup. Days later, Kardashian took to his Instagram to clear up those rumors and said he and Chyna were still going strong.

"Chy and I are not broken up we just feel like it would be a lot healthier for our relationship if we kept a lot more to ourselves," he captioned a cute close-up picture of the two of them. "It's impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate it if everyone respects that."
