The duo arrived on the island on Maui on Monday, mere hours after they shared a kiss during the Billboard Awards.
A series of photos of the young stars once again kissing have now emerged online, including one image where Gomez can be seen straddling Bieber on a beach .
Bieber and Gomez were also snapped sharing an embrace while on separate jet-skis and again while strolling down an ocean-side pathway.
The 'Never Say Never' singer took to his official Twitter account yesterday to comment on the pleasant weather for his and Gomez's Maui getaway, writing: "sunshine...aint complaining (sic)."
Both stars have remained coy about their romance in the past, but they recently were filmed kissing during a press conference in Indonesia and, just last week, Bieber professed that the Wizards of Waverly Place actress "makes [him] really happy".
