Harry's best friend got hitched and while many guests traveled from far and wide for the bride and groom, all eyes were on the prince and his girlfriend.
Markle wore a low key floral maxi dress and Harry donned a blue suit.
One guest told People magazine: "Harry and Meghan seem very much in love. It just feels very natural for them both. It feels easy — like they've known each other for a long time."
The couple stayed on the island at the luxury Roundhill Resort where cottages go for more than $5,000 a night.
Jamaica holds an interesting place in Markle’s heart, as it's where she married her first husband, film producer Trevor Engelson, in 2011. They divorced in 2013.
