The Instagram snap reminded us of something we've seen before - Bond girl, Ursula Andress's famous scene in 60s Bond film, Dr. No.
Rita's vintage-inspired bikini was a far cry from her usual bling-tastic tastes, but showed off the singer's amazing figure to perfection. We just wish we could get a closer look so we could work out where her bikini is from!
But Rita - who has been busy fighting off rumours that she's ditched BFF Cara Delevingne for a new 'wifey' - treated us to a close up of her ultra-glam, perfect red manicure in another pic. No 'au naturel' holiday nails for Rita!
We're totes in love with her friendship bracelets, too. Not to mention her a-mazing view.
Fancy a life-swap, Rita? Just say the word.
