She is an Instagram sensation boasting just shy of 20million followers.

And Demi Rose put on yet another sizzling display as she posed naked in a river during a lavish getaway in Costa Rica on Wednesday.

The model, 26, left little to the imagination as she showed off her incredible figure while skinny dipping under a waterfall.

The red and black camouflage printed top clung to her svelte frame while the draw-string thong bottoms left little to the imagination.

Accentuating her features with a hint of make-up, she let her dyed red tresses cascade down past her shoulders in voluptuous curls.

She captioned the jaw-dropping snap: ‘Rawr’ [sic].

The stunner later slipped into a plunging white two piece as she cooled off in the pool alongside pal Phoebe Parvin who joined her on the trip.

The duo made the most of the fantastic weather with a dip before enjoying a cocktail at the swim up bar.

Last week, globe-trotter Demi once more donned skimpy swimwear as she explored the island of St Lucia.
