The couple was seen taking it easy on a boat as they soaked up the sun and spent some quality time together on Friday.
Richie, 20, wore a white T-shirt with a pair of denim shorts, while Disick, 35, opted for a grey top with a pair of casual bottoms. Dressing for the weather, the pair accessorized their looks with sunglasses.
Although they have yet to share any photos from their vacation online, Richie posted plenty of photos from Kardashian’s birthday celebration as she cuddled up with pal Paris Hilton.
“Forever spirit animal,” she wrote alongside one photo of the pair smiling together at the star-studded fete.
