He's one more lonely boy!

Justin Bieber dropped by the chiropractor in his blue Lambo to get realigned yesterday, and the singer wasn't in the greatest mood as photographers peppered him with questions about Selena Gomez. Now we know why!

According to multiple reports, the lovebirds are giving their relationship some "space" after a string of disagreements.

"They weren’t getting along and decided to take a break. It doesn’t seem like a big deal and they will probably be fine soon again," a source told People.

The insider was quick to point out that they were never "officially" boyfriend and girlfriend again, and that they're still trying to navigate the exact nature of their romance.

"His relationship with Selena is really different [this time]. They’re not putting pressure on themselves. They have both been through a lot since the last time they dated so they’re getting to know each other again," the source added.

We hope Jelena isn't already dunzo!
