What's going on?! We spotted Justin Bieber at 3rd Street Dance studio twice this week and the obvious conclusion is that he's rehearsing for a surprise performance or a music video, right?!

Biebs was joined by wife Hailey Baldwin, on Friday, for about an hour and a half at the West Hollywood rehearsal space. The pair then enjoyed take-out sushi from Katsu-ya up the street.

Oddly, Hailey was holding her stomach as the couple made their way into their Sprinter van so let's just go ahead and launch the rumors ... pregnancy baby bump??? Uh, yeah :)
