Justin Bieber Sings on Instagram Live With Wife Hailey -- Watch!

The two appeared to be having a lot of fun together over the weekend.

Justin Bieber is having some fun with music!

Over the weekend, the pop star and his wife, Hailey Bieber, went on Instagram Live to give fans an update on their various projects. At one point, the two adorably broke out in song, with Justin taking the lead and Hailey joining in on the chorus to a song about his pal and musical director, Dan Kanter.

"Dan Kanter, we wrote this song for you," Justin croons, while Hailey gives him a beat by tapping on the desk and clapping her hands. "We hope you like it, we really do."

In another sweet moment from their live session, Justin couldn't stop passionately kissing Hailey on the forehead and cheek. "I love you, more than anyone," she gushed. 

Justin also teased Hailey for her beauty look, comparing her to JoJo Siwa, who is known for rocking oversized bows.

In addition to singing and chatting with fans, the lovebirds also got to spend some one-on-one time together, with Hailey posting a romantic photo of the two cuddled up together by the water.

"The Biebers," she captioned it.

Their fun-filled weekend comes shortly after Justin explained via Instagram why he took a break from music.

"So I read a lot of messages saying you want an album. I've toured my whole teenage life, and early 20s," he shared. "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."

"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 added. "Music is very important to me but nothing comes before my family and my health. I will come with a kick-a** album ASAP."

Justin's wife, Hailey Bieber, was one of the first to comment, showing her support with a sweet message. "That's right," she wrote. "Love you so much it hurts!!!"
