Fans of Justin and Hailey Bieber have been left shocked after the ‘Baby singer’ unfollowed his wife on Instagram.

Just last year, the celebrity power couple welcomed their first child together, a son they named Jack Blues.

“They’re both overjoyed,” a source told PEOPLE Magazine at the time. “The baby is such a miracle. He’s adorable and doing well. Hailey’s doing well, too.

“The pregnancy was something that they very much wished and prayed for.”

Prior to finding each other, Justin had famously dated Selena Gomez, while Hailey was said to have been involved with Shawn Mendes, another Canadian singer.

But the Biebers officially exchanged vows in 2018, which came after several years of an on-off romance between the pair.

Justin and Hailey wedded at an official ceremony in New York, which was followed by a religious service at the Somerset Chapel at the Montage Palmetto Bluff, North Carolina.

So, today’s development that Justin no longer follows his wife on Instagram has left much of the internet in shock.

“But why Justin Bieber has unfollowed Hailey Bieber on Instagram??” one person asked, while a second added: “Wow didn’t see this one coming.”

Meanwhile, a third offered their own theory, saying: “It’s most likely his social media manager running some awful marketing strategy.”

And a fourth remarked: “Why do celebrity couples these days start having issues after having a kid?”

Just recently, Bieber addressed the growing speculation he had split from his wife of six years.

The singer posted a photo to his Instagram Stories of his wife as they enjoyed a vacation in the snowy destination of Aspen.

“The greatest woman I have and will ever know,” Bieber added as a caption to the post as many came to the conclusion the pair’s bond was still strong.

The reaction from fans comes just a matter of days after many followers convinced themselves Justin is set to make an imminent return to the entertainment industry in the coming months.

Justin excited many of his fans after sharing a cryptic Instagram post last week alluding to a return to music by uploading a clip of himself listening to a seemingly unreleased track.

While it wasn’t confirmed for definite, the hint certainly suggests the ‘What Do You Mean’ hitmaker is making a return.
