The couple, who have several breakups and makeups in their history, were spotted together on January 2 in California and now last night Justin posted this intimate picture with the caption, "Love the way you look at me."
A source exclusively told In Touch earlier this week that the couple had rented Segways and were riding around Calabasas, Calif.
"Justin got mad that people saw them together and took photos but Selena was nice and didn’t seem to care," the source said at the time. “Looks like she is more okay with them going public together. Looks like they are starting the new year on a new foot."
However, that attitude may have changed, since Justin just shared a sweet black-and-white pic of him and Selena together on his Instagram, where he has more than 12 million followers.
Selena and Justin dated for about two years before splitting up in early 2013. Since the split, Justin has made headlines around the world for his bad behavior, including painting illegal graffiti in Brazil, losing custody of his pet monkey in Germany, and forcing his bodyguards to carry him up the Great Wall of China. Perhaps Selena's return will be a calming influence for him?
Justin tweeted recently that he is retiring from music following the release of his documentary "Believe." That retirement ought to leave way more time for spending with his girlfriend.
