The couple had only made their reunion Instagram official on March 1st - when Sel took to the social-media platform to pen an emotional message to her "super cool" boyfriend on his 24th birthday.
But hold your horses, because Justin and Selena aren't quite as settled as most people expected. According to E! the couple have decided to "give each other some space" amid the constant media scrutiny into their relationship.
An insider claimed that the duo have been bickering recently, but hinted that their romance is far from over: "They were having a lot of little disagreements recently and one fight in particular blew up and caused them to decide to 'break up'.
"However, they've been in contact the entire time and their feelings for each other have not changed," the source added. "They will absolutely get back together and they are not over, but they both need some time away from each other."
The duo haven't had the smoothest relationship of all time, with their latest reunion reportedly causing a bit of friction between Sel and mum Mandy Teefy - who, by the sounds of it, isn't exactly the most committed Jelena shipper the world has ever seen.
All in all, it sounds like this is just another chapter in the long, complicated, and ultimately very confusing Jelena saga.
Until next time, folks.
