It seems like the on and off relationship of Selena Gomez and Justin Bieber is at it again!

Bieber posted on Instagram, but immediately deleted, a picture of him and his ex. In the photo the "Boyfriend" singer was holding Selena, while she planted a kiss on his cheek.

According to E! online, before removing the image, the 20-year old singer captioned the photo as:

"Right now everything else is a blur,"

Bieber has posted and deleted photos of his famous ex multiple times in the past.

There has been no confirmation whether or not the former lovers are back together. However, the recent photo posted indicates something fishy going on between Selena and Justin.

Last June, a source from E! news said the former couple wanted to give their relationship another try:

"She still loves him,"

"It is hard for her to get over him because they have so much history."

The source further said:

"You just can't drop those feelings,"

"There is too much there."

Selena Gomez and Bieber were seen many times together last June. Justin was even part of the guest list in Selena's birthday bash last July. But, things were ruined between the two before something even got started.

Just more than a week before Selena's birthday, an E! news source said:

"There will forever be an emotional connection for them, but they don't have a title to their relationship,"

"He is not her boyfriend, but the feelings are always going to be there."

The insider emphasized that Selena Gomez "is trying to move on with her life and focus on her.", according to E! online.
