Justin Bieber just sparked speculations that he could be working with his wife, Hailey Baldwin, on his new album. The “Baby” singer uploaded a cryptic photo on his Instagram account last weekend.

In the snap, Bieber is sitting in front of the piano playing and whipping up a tune. Behind him is Baldwin, who is looking straight into the camera while hugging her husband. The intimate photo also shows Bieber without a shirt on. Baldwin, on the other hand, is wearing a sports bra and jogging pants.

As of late, Bieber has not yet announced his plans for a new album. But the last time he has released a full album was in 2015. Following the release of the singer’s “Purpose” album, Bieber has gone on almost full sabbatical from the music industry.

Last year, he dropped his collaboration with Ed Sheeran called “I Don’t Care.” But with the exception of the hit track, Bieber has opted to live a quiet life, away from the public’s eye. Earlier this year, he also explained his decision to focus on his mental health.

“I’ve toured my whole teenage life and early 20s, I realized as you guys probably saw I was unhappy last tour and I don’t deserve that and you don’t deserve that,” he wrote on Instagram. “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 added.

And during an interview with Vogue, the award-winning singer also opened up about his battle with depression and his addiction to Xanax. Bieber said that he reached a point in his life when he became ashamed of the things that he was doing.

“Drugs put a screen between me and what I was doing. It got pretty dark. I think there were times when my security was coming in late at night to check my pulse and see if I was still breathing,” he said.

The singer also said that thinking about music stresses him out. “I’ve been successful since I was 13, so I didn’t really have a chance to find who I was apart from what I did,” he said.
