Is it a water nymph? Is it a mermaid? No, it's supermodel Kate Moss! More specifically, it's gorgeous model Kate Moss on holiday in Formentera, in the Pitiusic Islands (that's next to Ibiza).
You know what celebrities on vacation means? Sexy, outrageously gorgeous bikini shots, that's what. Dripping wet, semi-naked women frolicking in the ocean. Or a pool, or whatever. There's hot, wet babes. That's a good thing.
You can almost feel the salty spray, can't you? Have a nice day, lustful viewers.
