The Love Yourself hitmaker took to his Instagram Story to confirm that it was not him who hit the unfollow button on the Rhode Beauty founder's page – amid speculation the pair were heading for a divorce.
Bieber wrote: "Someone went on my account and unfollowed my wife. S*** is getting suss out here."
The 30-year-old pop star – who has five-month-old son Jack Blues with the 28-year-old model - also re-followed his wife on the social media platform.
The couple have faced a string of rumours they were splitting since they married in 2018, but Bieber recently brushed off the gossip in a New Year post.
He commented on a series of photos posted by Hailey on Instagram to ring in 2025, which showed her posing in a bikini: "Um. Goin anywhere with u bb. Happy new year. (sic)"
Hailey captioned her carousel of images: "Wake up, it's 2025!"
It included snaps from the couple's New Year's Eve party, which included caviar-topped In-N-Out burgers and martinis.
A source recently told Page Six she and Bieber "couldn't be happier" while "adjusting to life as parents of a newborn".
They added: "Hailey has seen a whole different side to Justin since becoming a father and she's more in love with him than ever."
The source admitted even though "every day is a learning experience" for the pair, they are apparently "loving navigating this new chapter together".
They went on: "Hailey feels incredibly blessed to be celebrating her first Christmas as a mum.
"When Justin asked Hailey what she wanted for Christmas this year, she really couldn't think of anything because she has everything she could ever want."
The insider also said even though the pair "have discussed having more kids" in the future, they are "happy with where things are at" in their lives.
