From her perfectly styled hair to her elegant floral dress, the Suits star gave off major Kate Middleton vibes, while Prince Harry looked dapper in a white dress shirt and slacks. At one point, Markle sweetly put her hand around her beau's back while the two were sitting at a table, drinking champagne with another guest.
The lovebirds reportedly arrived in Montego Bay on Thursday -- Markle arrived via private jet, while Prince Harry reportedly paid approximately $3,000 for a commercial flight slightly better than coach.
"This is a big event for Prince Harry, because it's one of his best friends getting married," ET royal correspondent Katie Nicholl explained before the two touched down in the Caribbean. "It's a big deal for her to be going as his plus one. This wedding will be a huge amount of fun. There will be a lot of alcohol going down."
