Justin Bieber is hitting back at “immature” online trolls who question the strength of his marriage to Hailey Baldwin.

He penned a long response to one Instagrammer who implied he is still in love with ex Selena Gomez.

“I absolutely loved and love Selena she will always hold a place in my heart,” the singer wrote in part. “But I am head over heals [sic] in love with my wife and she is absolutely the BEST THING that has ever happened to me period.”

Justin went on to say that he and Hailey have received multiple hate messages from trolls and, while he doesn’t normally like to give them attention, he felt the need to make a blanket statement.

“This is a reply to all immature sick people who send Hailey hurtful messages like ‘he always goes back to Selena’ or ‘Selena is better for him,’” he wrote. “YOU HAVE NO IDEA MY LIFE AND WHAts good for me!! Hailey is my Bride period if you don’t like that or support that that means you don’t support me.”

Justin posted a screenshot of his response to his Instagram Story and urged his fans to share.

“Stop sending hailey and I these messeges [sic] if you love me screenshot this and repost everywhere,” he writes.

On Monday, Justin penned another emotional post where he explained that he’s taking a break from music to focus on his mental health and relationships.

"I’ve toured my whole teenage life, and early 20s, I realized and as you guys probably saw I was unhappy last tour and I don’t deserve that and you don’t deserve that, you pay money to come and have a lively energetic fun light concert and I was unable emotionally to give you that near the end of the tour," he wrote.

"I have been looking, seeking, trial and error as most of us do, I am now very focused on repairing some of the deep rooted issues that I have as most of us have, so that I don’t fall apart, so that I can sustain my marriage and be the father I want to be," he continued.

"Music is very important to me but Nothing comes before my family and my health," he added.
