The 21-year-old 'TOWIE' babe showed off her killer curves in a black two-piece as she went for a dip near the Grosvenor Beach Hotel.
The loved-up pair looked tanned and happy as they shared a kiss in the sea and took a stroll hand-in-hand along the beach.
The couple - who split up for four months last year - have both talked about getting married in the future.
And you'd be forgiven for thinking 23-year-old Joey was going to pop the question during their trip after he posted a cryptic tweet.
"Having a nice relaxed time in Dubai! Weather is perfect. Off out tonight to surprise @SamanthaFaiers ;-) .. She doesn't know anything.. Shhh," he wrote.
We'll be keeping our beady eyes on Sam's fingers when they arrive back in the UK later today.
