Justin Bieber has shared a photo of a mystery female's bum on Instagram Thursday, Sept. 25, but Jelena fans have nothing to worry about, as the unidentified woman seems to be Selena Gomez. Check out the photo below.

The image shows a brunette female standing before a bed of red flowers. With her back to the camera, the lady - whose long wavy tresses are flowing around her shoulders in a natural fashion - shows off her enviable behind in a form-fitting navy blue body con dress.

Apparently, the 20-year-old "As Long As You Love Me" singer tastefully zoomed in on the woman's derriere, presumably to brag about what his 22 million Instagram followers are missing, according to EntertainmentWise.

Meanwhile, the on-again, off-again couple is reportedly ready to live together under one roof.

"Selena and Justin are a hundred percent together right now, he's asked her to move in with him and she couldn't be happier," a source told Hollywood Life.

But the tipster claimed that the 22-year-old "Come & Get It" singer will keep her place, so she still has her own sanctuary to go to anytime she needs some space.

"She's still being cautious, she's not going to give up her place, that way if anything goes wrong or if she decides she needs some space, she'll have her own spot to go to," the source explained. "But, officially she's going to be living with him. It's a huge step."

Though the lovebirds have had their share of trust issues in the past, it seems that they have already worked those stuff out.

"Selena trusts him. She had to let go of her jealousy and stop worrying about other girls. He's promised her that she's the only one, and she believes him," Hollywood Life's source continued. "Since they got back together, he hasn't given her any reason to worry - so she's not going to."

The pair made headlines late last month when Bieber was arrested for assault and dangerous driving while on a "peaceful retreat" with Gomez in his home city in Stratford, Ontario, following a collision between a minivan and an ATV that led to a physical altercation involving a photographer, according to People.
