Justin Bieber proves that he can still sing during Hailey's IG Live

If you were afraid that Justin Bieber taking a break from the music would affect his singing abilities – do not worry, he certainly still has the means … as you can see here.

The Biebs made an appearance on Sunday during HaileyInstagram Live session – where she was trying to connect with a professional surfer Kelia Moniz plug in the sportswear company Roxy. Both of them are brand ambassadors, and Roxy even teased their conversation together.

While Hailey waited for Kelia's online connection, her husband appeared behind her and began to sing an invented tune dedicated to her former senior guitarist. Dan Kanter. Apparently Dan was one of the many people to have listened to and commented on Hailey's video.

Hailey reported it to JB … and he took it away with an impromptu jam. Considering that we have not heard much about Bieber pipes exposed recently, it must be said … it sounds good.

More importantly, Justin seems to be in a good mood. This comes on the heels of his recent announcement that he is away from music for a while to deal with some "deep-seated issues" … as well as information that he was seeking treatment for depression.

Also worth noting … this offers a rare glimpse of how married couples interact with each other in the comfort of their home. Look at this … they are really cute together.
