Rob Kardashian and Blac Chyna on a vacation to Jamaica

Running away from the drama! Rob Kardashian and Blac Chyna flew first class from Los Angeles International Airport to Montego Bay, Jamaica, on Saturday, March 12, just days before his 29th birthday.

Kardashian, 28, looked a lot slimmer in black sweats and sandals as the couple headed off on their romantic getaway. “They both looked happy, but showed no signs of affection,” an eyewitness told us.

Chyna, 27, initially revealed their destination on Snapchat, where the pair both posted a series of photos and videos documenting the plane ride. The model is set to appear at BritJam on Sunday; the week-long event is described on its Facebook page as the largest Spring Break Festival in the Caribbean. #montegobay #springbreak #jamaica #goodgoodproduction #pdpentertainment #britjamofficial #erricealicia #skkanme @SkamArtist #SkamLife

Kardashian and Chyna first revealed their relationship in January, much to the dismay of some members of the Kardashian-Jenner clan. A source close to the family previously told us that Khloé Kardashian “feels 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 engaged to Kylie Jenner’s current boyfriend, Tyga, and the exes share a 3-year-old son, King Cairo.
