Taking advantage of what looked like a gloriously sunny day, the Essex starlet opted to tie her leopard print cover up around her waist and show off her demure black bikini to everybody.
Well, if you have a bikini bod like that, why not?!
We chatted to Ferne last year about her sunshine holiday essentials - apart from a slew of bikinis, of course!
"I would never dream of going on holiday without a pair of flip-flops - always Havaianas. They come everywhere with me, especially on holiday. A really good pair of sunglasses. I definitely splash out when it comes to sunglasses. I think you should invest in a really timeless pair. I like Miu Miu, because they have more alternative shapes that you wouldn't see everywhere and they are always on trend and really cool."
Ferne is over on the Spanish holiday island with a string of co-stars to film scenes for the brand new series of The Only Way Is Essex, which returns to ITVBe on Sunday, 22 February at 10pm.
Unfortunately for the Essex boys, it's a girls' only holiday (with the exception of Bobby Cole Norris and Vas J Morgan), meaning Ferne's boyfriend Charlie Sims is back home.
Just one day into the trip, Ferne tweeted about how much she was missing Charlie, adding the hashtag #love.
