Wow. Rob Kardashian is looking SO good!
On Saturday night, the 28-year-old and his girlfriend Blac Chyna left LAX for a quick trip to Jamaica, and even in sweats, he was showing off all the fitness progress he's been making.
The reality TV star has definitely slimmed down!
He and his beau decided to jet off to Montego Bay for Chyna's appearance at BritJam, a spring break festival, so it wasn't entirely a vacation for the couple… even though his birthday is only days away!
But while Rob never made it on stage with his boo, fans caught sight of Kris Jenner's only son taking in the show. See for yourself (below):
