Fans have always thought that there's a bit of tension between Justin Bieber and Nick Jonas for obvious reasons. In case you've forgotten, both heartthrobs dated Selena Gomez in the past!

Of course, everyone has moved on at this point but, we didn't know that meant JB and Nick became friends after it all went down! The "Levels" singer posted a photo yesterday on social media featuring him and the Biebs. He captioned the shot, "Flashback @justinbieber ??."

Flashback @justinbieber 🙌🏼

Ahh! So even though this might not be a recent photo, it just goes to show that they still keep in touch and are definitely friends! The two pals look like they are either dancing, laughing, rapping or singing in the moment and to be honest no matter what is going on it's just literal proof that they have a bond.

Do you think they have ever chatted about Selena while hanging out? Do you think she gets upset when she sees pictures like this? Sel IS still good friends with Nick so we're not sure how she feels that he's talking to JB who she has seemingly cut all ties with.

Not only that BUT, could this be a hint about a future collaboration? Like can you freaking imagine Nick and Justin singing on the same song? Music GOALS, right there.

Really, there are just too many questions to be answered now that this photo has surfaced. Nick, Justin, Selena – any and all answers would be greatly appreciated!
