Over the past few weeks, fans of the former couple Justin Bieber and Selena Gomez have seen an interesting throwback picture on social media that showed the two kissing each other, as well as Gomez attending Bieber’s Los Angeles concert. A source has now reportedly said that the Canadian singer has been trying to rekindle a romantic relationship with his former girlfriend.

A source told E! News that Bieber has been “trying to get back” with his former girlfriend. The “What Do You Mean” singer even wanted to rent out the Staples Center in Los Angeles so that he could surprise Gomez after his LA concert Wednesday. The source said that Bieber had planned to “do a repeat date night screening of ‘Titanic’” with the former Disney actress.

The source added that Bieber had been “making arrangements for the movie date before his concert even started.” The romantic evening was also reportedly “something big and extravagant” that the singer had been planning to do for his former girlfriend. However, Bieber ended up cancelling the planned romantic date.

"I don't know why he didn't go through with it, and I also don't know if he ever even told Selena about his plan, but I do know he is really obviously trying to date her again," the source said.

Another insider told E! News that the singer’s mood had been “off.”  

"During his concert between songs, he was alluding to the fact that he wasn't happy to be there. At one point during the concert he was just lying on the stage not singing, just letting the track run," the insider said, referring to the singer's performances during his Los Angeles “Purpose” concert.

Speculation points to Bieber and Gomez potentially having an argument before the concert started, a source told E! News. Despite romance speculations, another insider said that the two celebrities are “not dating” and that “nothing romantic” is going on between the former couple.

Meanwhile, the “Hands to Myself” singer and Bieber have been “liking” each other’s throwback pictures on Instagram. Gomez recently posted a throwback picture of herself playing a piano while wearing a colorful bikini in a Texas house. On the other hand, Bieber uploaded a throwback image of himself and Gomez kissing each other while inside a pool. The Canadian singer captioned the image, “Feels.” Gomez was said to have “liked” the photo on Instagram.
