Justin Bieber's been busy jumping on the St Barths/Anguilla bandwagon this week, only unlike *some* people he's not just been lazing around on a yacht.

Nope, he's instead used the ridiculously romantic location to serenade his rumoured girlfriend Hailey Baldwin, a la One Less Lonely Girl.

Anyone else reckon he learnt Tom Jones's 'Sex Bomb' for the occasion?

Biebs also explained that it was the "Best environment to write music other than right after a heartbreak", so we can only imagine what he'd produce if he was heartbroken ON AN ISLAND.

Oh and then he climbed a tree, perfectly illustrating us clinging on to the hope that Harry Styles might tweet us one day.
