The 27-year-old singer, who has been married to Hailey since 2018, shared a picture of the couple on social media on Monday.
Under the picture, which he posted on Instagram, he wrote the caption: “Mom and dad”.
Some of the singer’s 183 million followers thought it was a hint the couple were expecting their first child.
Model Hailey, 24, took to the comments section to end any speculation. "I think u should maybe change this caption to *Dog Mom and Dad* before anyone gets it twisted,” she wrote.
Some fan comments included: “Baby on the way?" and "Wait what? MOM AND DAD?!"
The post came after Hailey spoke out after a video that appeared to show her husband Justin shouting at her went viral.
The model shut down the speculation the couple were fighting in the video as “negative bulls***”.
As fans screamed Bieber’s name, the clip showed the pop star in an animated conversation with his wife of more than two years.
The model gushed about her “amazing” weekend with her husband on social media.
Alongside a picture of the couple kissing, she wrote on her Instagram stories: “Reminiscing on how amazing last weekend was. Had the best time surrounded by so much love.
“Any other narrative floating around is beyond false. Don’t feed into the negative b******t peeps.”
