Selena Gomez And Justin Bieber 2013: Jealous Over Picture? ‘Heartbreaker’ Star Poses In Revealing Photo

Justin Bieber was spotted posing in a revealing shirtless picture earlier this week, leaving fans wondering if he was trying to get Selena Gomez jealous.

Justin Bieber also responded to questions asked by several paparazzi about ex-girlfriend Selena Gomez after attending a business dinner and mentioned that "she's great" after being asked about his relationship with her.

One photographer shouted, "Justin, how's everything with you and Selena? You guys still buds?" the Inquisitr reports.

"Selena's great," he replied, repeating, "Yeah, she's great," when the pap interjected with "really?" the Inquisitr also reports.

But the couple's reunion might not be official just yet.

Selena Gomez posted a picture on Twitter of herself posing with action star Ethan Hawk during a photo-shoot for their upcoming "Getaway" film, leaving fans wondering if she's crushing on him.

While Selena Gomez has mentioned repeatedly that she is single and that she is looking to date other men, one source close to the "Come And Get It" star revealed she's nowhere near ready to move on.

"Selena is still not over Justin, not even close," a source told HollywoodLife.com.

"[Going on a date] with George [Shelley] started as a way to make Justin jealous, but now it's taken on a life of it's own. They're going to meet up when she heads to Europe so who knows? It might actually turn into a good thing and help her get her mind off of Justin - but from what all her friends are saying, she's still majorly hung up on Justin."
