When Justin Bieber took high school student Cady Elmer as his date to the Billboard Music Awards on Sunday, we immediately began to wonder what was going on with ladylove Selena Gomez.

Sure, he said the 19-year-old starlet was shooting The Getaway in Bulgaria, but even if she wasn't able to accompany him, we highly doubt she'd be ok with him taking another girl in her place. Justin didn't even think to mention Selena in his acceptance speech at the show, and all kinds of evidence has popped up this past week which has us questioning whether these two teenage lovebirds are even together anymore!

Selena recently deleted her Instagram account (you know, the one with ALL those cutesy snapshots of the couple), and a few days ago she uploaded a photo from the gun range and wrote, "released some stress today."

Jelena haven't been photographed together since the former Wizards of Waverly Place starlet paid him a visit on the set of his "Boyfriend" music video over a month ago, and Justin reportedly posted a very cryptic message last week on Twitter, writing, “thank you for the time i had with you, but i have to move on now." Manager Scooter Braun insists it was fake, but several websites screen grabbed the alleged tweet, so it definitely existed somewhere!

Additionally, there was a 5.6 magnitude earthquake in Bulgaria this morning, and while Selena tweeted her fans to let them know she's fine, Biebs hasn't posted anything to his account about it.

Reps for the young stars have yet to respond to our request for a comment on the matter, but we'll keep you posted!
