The on and off young lovers broke up last month, but it seems they have sorted out their differences after they were spotted kissing at a Salt Lake City airport on Friday.
Selena sat on her boyfriend's lap as the pair indulged in a steamy kissing session while waiting for their flight.
But it seems that not everyone is happy that the couple have reunited, as Selena has received a barrage of abuse from Justin's devoted fans on Twitter.
'Go back to your own friends and family. let justin breath and get your tongue from down his throat @selenagomez,' (sic) wrote one of his followers.
While another wrote: 'Your relationship is faker than joan rivers face @justinbieber @selenagomez'
Lol these children won't kill me.
