The photo caused a frenzy amongst the 21-year-old pop star's followers, as some Beliebers noted that the intimate snap looked just like one he took with his on-again, off-again girlfriend, Selena Gomez, in October 2014.

Baldwin's post was followed up with a photo of her standing on a ledge, overlooking the crystal clear water. "First day of 2016 not lookin too shabby," she wrote.
