While at first he only sings to Hailey, he turns to get the attention of a stranger standing nearby.
Justin grabs the stranger's hand, and then pauses so the two of them can take a photo together. But then, he starts singing again.
Unfortunately, throughout the whole performance, Hailey doesn't seem to be vibing off it at all, and continued to wander away and turn from her husband as he performs.
