Justin Bieber is happily married to wife Hailey Baldwin, but one photo he liked on Instagram recently had fans wondering whether he is still hung up on ex-girlfriend Selena Gomez.

Instagram account @JustinOutfits recently shared a set of "rare/unseen" photos of Bieber, including an old snap of him and Gomez engaging in some sweet PDA. The throwback photo showed Gomez sitting on Bieber's lap, with an arm around his shoulders. The two appear to be smiling and talking intimately in the snap that seemed to have been taken backstage of an event.

According to Cosmopolitan, the "Love Yourself" singer liked the post, as shown here. However, it is unclear whether or not Bieber even saw the old photo of him and Gomez as it was the second snap in the post. The first image showed a picture of him with Katy Perry, so this may have been the reason why he liked the Instagram user's post.

But regardless of what the rumors say, Bieber himself made it clear that he was completely loyal and in love with his wife. Last week, he clapped back at a fan, who commented on a photo he posted of Baldwin on Instagram that he was "not in love with Hailey."

The Instagram user with the handle @JaileyIsAJoke claimed that Bieber had only tied the knot with the model last year to "get back" at Gomez and that Baldwin "sleeps with men like Shawn Mendes for fame." The follower also called Baldwin "racist."

Bieber quickly came to his wife's defense, calling out the Instagram user for being "immature" and having an account solely dedicated to bashing their relationship. He said that anyone who believes that he would dedicate his "whole life to someone in marriage to get back and my ex" is "mean spirited or 10 years old or younger."

The "Sorry" hitmaker also clarified that while he loves Gomez and that she "will always hold a place" in his heart, he is head over heels for Baldwin, whom he describes as "the best thing that has ever happened" to him.

“Hailey is my Bride period if you don’t like that or support that that means you don’t support me and if you don’t support me your not a fan nor a good person, if you were raised right your parents would have said if you don’t have something nice to say don't say anything (sic)," he concluded his tirade.
