Justin Bieber and Selena Gomez are apparently back on.

The 20-year-old posted a video of himself singing and running towards Selena Gomez recently. The video was deleted soon after it was posted, according to HollywoodLife.com.

In the video, a shirtless Justin Bieber is pumping his arms in the air and smiling at the camera. The "Boyfriend" singer starts jumping around in the video before the camera pans, showing Selena Gomez bending over and laughing at Justin Bieber's antics.

Speculation that Justin Bieber and Selena Gomez are back together was further fueled with Biebs posting an Instagram message about "walking away from the drama and loving the people who treat you right."

We can't deny that Gomez has stood by Bieber for some time now.

The troubled singer and his on-again-off-again ladylove were seen cuddling up on August 11, according to the website. The couple reportedly went another "secret" date on August 14, even posting a picture of themselves being affectionate with one another on Instagram.

Along with the picture of Selena Gomez kissing Justin Bieber's cheek, the Canadian singer posted the caption, "Right now everything else is a blur."

A source for HollywoodLife.com reportedly told the website that Justin Bieber and Selena Gomez getting back together was only a matter of time.

"As far as them getting back together, it's kind of a matter of when, not if. Hopefully when it does happen he'll finally be ready to treat her properly," the source told the entertainment website.
