The photo of the much-younger couple shows the two kissing while standing in a pool. Bieber captioned the photo, "Feels."
It's not the first time Bieber has posted an old photo of his former flame. In December, he shared a photo of them sitting very close on a red ATV. The "Sorry" singer's caption cleared up any dating rumors right away. He wrote, "Just a throwback calm down."
Still, it seems Bieber, 22, hasn't let up since he pleaded for Gomez's forgiveness on his latest album "Purpose." He even said during an appearance on "The Ellen DeGeneres Show," last November that he's open to getting back together with Gomez someday, adding, "I just want her to be happy, honestly."
Meanwhile, Gomez, 23, said she's over the relationship, which began in 2011. The two have been dating on and off for years.
"I’m so exhausted," she told W Magazine last month. "I honestly am so done. I care about his health and well-being. But I can't do it anymore."
