Selena Gomez reportedly filled her mind with thoughts of Justin Bieber during her recent sexy, cover shoot for V Magazine.

Hollywood Life is reporting the 22-year-old "Come & Get" crooner solely concentrated on Bieber as she posed for shot after shot and was even more inspired by the thought that he would eventually see each and every photo published.

"Selena did the V Magazine photo shoot in December, and Justin was still the only thing on her mind," a source said. "She was thinking about Justin when she was posing -- she was trying to look as sexy as possible, and he's the guy that brings that out in her. Especially when she did this shoot."

Gomez and Bieber have since gone their separate ways. and she is now rumored to be dating Zedd, though Bieber recently vowed to win her back.

Bieber reportedly has now seen the pics and is a "big fan" of them.

"From her cleavage revealing Instagram shots to her sexy video shoots she's showing a whole new side of herself that Justin has never seen," the source said. "Selena's recent sexy magazine and video shots are driving Justin absolutely insane. He can't believe how hot she looks. His jaw hit the floor. It's like she has this whole other personality completely different from the one he dated."

Several media outlets recently reported the 20-year-old Bieber remains so enamored with Gomez he still considers her to be "his girl" and would "get into a fight" with Zedd for the chance to win her back.

"Justin would have no problem at all getting into a fight with Zedd over Selena," the source said. "He's in the best shape of his life and his emotions with regard to Selena are running as a high as a kite. I would not recommend them being in the same room."
