While Bieber often publicly reminisces over the pair's romance, the timing of his throwback is a little odd, as Gomez was reportedly spotted kissing and hugging One Direction's Niall Horan at a Los Angeles party the night before.
In the image, taken during the former couple's on-and-off-again relationship from 2011 to 2014, Bieber and Gomez are seen holding hands.
"Crazy throwback," Bieber, 21, captioned the photo.

While Bieber also posted an older image of himself and Rihanna on Saturday, the Gomez picture definitely generated more buzz as the 23-year-old was spotted dancing close to Horan all night on Friday at Jenna Dewan-Tatum's 35th birthday bash.
The flirtation with the U.K. boy bander comes just after the "Same Old Love" singer told InStyle UK that she struggles to get dates because she looks "16 sometimes."
One person she isn't getting involved with at the moment? Bieber. A source recently told PEOPLE that the former couple are "not getting back together right now."
