The tween princess and and the "Baby" singer, who previously denied they were a duo, were snapped in a series of pics (featuring the 16-year-old Bieber shirtless) looking cozy, cuddling and kissing each other on a yacht in St. Lucia in the Caribbean.
But instead of being happy for their heartthrob, some fans have taken their Bieber fever too far with angry Tweets aimed at Gomez....
"I'll kill you I swear to GOD!!!!" wrote one fan while another offered "If you are the Girlfriend of Justin I will Kill you I HATE YOU :@!!!"
Take it down a notch, people.
Their romance became public back in early December, when the twosome were spotted getting cutesy in Miami, where they were almost, sorta holding hands on a stroll together.
"We just like to hang out. They shouldn't be stopping us from going out to dinner and things like that," Gomez told People last month.
Although, to be fair, some of the newer tweets have proven supportive, with one Tweeting to Gomez, "I'm just happy to see you happy xoxo."
Reps for the pair have been contacted, but have not yet replied for comment.
