The Lauren's Way owner showed off her slim figure in the backless, knee-length dress as she posed for a photo with Jake on Monday night (24 June).
How bronzed does Lauren look?! Either the results of the Caribbean sunshine or a dose of her Lauren's Way darker than dark tan. Maybe both!
Lauren's fans were quick to comment on the loved-up picture, with one saying: "Stunning Girl Stunning Boy ... Imagine the babies."
Earlier in the day, the ex-TOWIE star had sent Jake a public message, saying: "Happy Birthday 2 u Happy Birthday 2 u Happy Birthday 2 my baby Happy Birthday 2 u @McleanJake love u loads looking forward later x."
Lauren and Jake arrived in the Caribbean earlier this month for their first holiday together.
Sun, sea, sand, a killer dress and all loved-up? Lucky Lauren!
