Selena Gomez is still reportedly pining for Justin Bieber, putting her current relationship with boyfriend DJ Zedd in grave danger.

According to HollywoodLife, 22-year-old Gomez has never completely gotten over first love Bieber, apparently driving a wedge between the "I Want You To Know" singer and 25-year-old Zedd.

Star Magazine even reported the two have called it quits, though some close to the couple insist such declarations might be a bit premature.

"They're not broken up, but there've been some bumps in the road," a source told HollywoodLife. "Selena can be very dramatic and that's totally not Zedd's style, so he has a hard time dealing with it."

Zedd is allegedly asking Gomez to completely forget about Bieber, but if rumors are true, this appears to be harder said than done for her.

"She's still not over Justin," the source added. "She asks people about him and finds little ways to bring him up. It bugs Zedd that she still cares so much about Justin and what he's doing, and even though he tries to be chill about it, it's getting hard to take."

Bieber, 21, is expected to release a new album soon and speculation is he could choose to croon a tune or two about his ex on the track. Such anticipation reportedly has Gomez more concerned about what he's up to than ever before.

"Selena is really worried that Justin is going to write about her in his new music," a source told the website. "She's freaking out that he's going to diss her and she doubts he's going to let her listen to his music before it's released."

HollywoodLife recently reported Bieber plans to use his experiences with his ex as "complete motivation" for his soon-to-be released album.

At the beginning of the year, Bieber vowed to win back Gomez, regardless of what changes it might take in his personal life to do so.
