Justin Bieber and Selena Gomez hadn't been seen together for almost a month ... until Wednesday night.
Justin and Selena were leaving a Hillsong Church service in L.A. when he spotted photogs, gave an audible grunt, and then got downright sarcastic when they screamed Selena's name.
Earlier in the day Justin hit the ice for a little hockey and Selena watched rinkside snapping pics.
The last time we saw them was at a Pilates class just after the Christmas holidays, but clearly they're still tight.
